This axial-radial bearing with dimensions of 150mm ID x 240mm OD x 40mm is for heavy-duty CNC machining centers, indexing heads, and precise automation equipment. Luoyang Auto Bearing Co., Ltd. (ATLYC) is a 15-year-old ISO 9001 and IATF 16949 certified manufacturer. This bearing is supplied to customers in the USA, Germany, South Korea, and abroad. ATLYC offers reasonable prices, confirmed quality, and scalable production capacity.

YRT 150 High Precision Rotary Table Bearing is a particular axial-radial bearing for situations where micron-level runout precision is critical. It contains a thrust bearing, a radial bearing, and an index mechanism in a single compact module. The outer ring is the fixed ring; the inner ring is the precise rotary ring. The bearing is designed with two rows of steel balls with contact angles of 45° or 60°, which allow the bearing to support axial loads, radial loads, and composite tilting moments concurrently.
The raceway surfaces are ground and super-finished to precise tolerances to provide surface roughness levels that reduce friction, preserve the lubrication layer, and significantly increase service life. It is made from high-quality GCr15 bearing steel and heat-treated to 58-62 HRC so that it can retain its dimensions even under high tilting moment situations. The axial static load capacity is 400 to 500 kN, and the radial static load capacity is 150 to 200 kN. The precision class is ISO P4 or P2 according to the ISO standards. Axial runout is limited to 3-5 micrometers.

Quality inspection protocols for this rotary table bearing include CMM and Taylor Hobson roundness verification, starting torque testing for preload consistency, metallographic hardness analysis, and raceway surface roughness (Ra) measurement. These controls ensure each unit meets the tolerance demands of 4th- and 5th-axis CNC machining centers, precision indexing heads, and large-format metrology equipment.
The first step in choosing the proper rotary table bearing is to know the dimensions and load limits. The YRT 150 High Precision Rotary table bearing is suited to smaller footprint, lighter-duty applications, whereas the YRT 180 manages higher tilting moments in larger machining platforms. The YRT 150 is available in the perfect range of mid-size 4th and 5th axis tables where space restrictions and load requirements meet.
The cross roller bearings provide excellent stiffness in a flat profile but need more accurate housing preparation and do not combine the radial and axial load courses as well. Direct drive bearing systems may operate at high speeds but are much more expensive and complicated. YRT 150 High Precision Rotary table bearing is the practical solution when you need tilting stiffness, zero-backlash placement, and compact assembly at the same time.
| Bearing Type | Load Integration | Backlash | Installation Complexity | Cost Range |
|---|---|---|---|---|
| YRT 150 (Axial-Radial) | Axial + Radial + Tilting | Zero (preloaded) | Low (integrated unit) | Moderate |
| Cross Roller Bearing | Axial + Radial | Low | Moderate | Moderate–High |
| YRT 130 | Lower capacity | Zero | Low | Lower |
| YRT 180 | Higher capacity | Zero | Low | Higher |
| Direct Drive Bearing | Axial dominant | Minimal | High | High |
European brands like NSK and SKF manufacture comparable axial-radial bearings at premium price points, often with lead times that challenge fast-moving production schedules. For OEMs and distributors prioritizing cost-performance ratio without sacrificing precision, certified Chinese manufacturers now deliver equivalent P4/P2 class accuracy with shorter delivery windows and stronger bulk order flexibility.
Procurement professionals sourcing a YRT 150 rotary table bearing in the United States and globally should prioritize manufacturers holding ISO 9001 and IATF 16949 certifications, as these validate consistent process control and traceability. Direct manufacturer purchasing reduces counterfeit exposure, which remains a documented risk in high-precision bearing markets.
Here are the primary sourcing channels worth evaluating:
Together, these sourcing methodologies provide a good base for procurement teams to conduct authenticity validation and manage supplier risk. Counterfeit YRT series bearings will usually fail dimensions and hardness tests; therefore, it is still the most reliable way to verify by seeking CMM reports and material hardness certifications before shipping. Usually 8-15% cost savings plus priority scheduling for manufacturing on bulk orders. Average shipping time from Chinese manufacturers to US ports is 18–30 days, depending on transit method.
The YRT 150 High Precision Rotary table bearing delivers measurable operational advantages across CNC machining, automation, and metrology applications. Here are the core advantages that make it a preferred choice among industrial manufacturers:
These benefits solve three of the most stubborn pain issues in precision manufacturing: positioning error build-up, unexpected downtime due to bearing fatigue, and over-engineered multi-bearing assemblies that increase both cost and the chance of failure. Manufacturers that have used this rotary table bearing in 4th- and 5th-axis tables have reported repeatability of placement within ±2 arc-seconds, a standard that directly supports aerospace, automotive, and medical component manufacturing tolerances.
Proper installation of a precise rotary table bearing will decide whether it operates to spec or degrades prematurely. Integrated mounting holes are available in the inner and outer ring of the YRT 150, which simplifies alignment and remove the need for a separate bearing housing retainer, a true installation advantage over traditional combined bearing arrangements.
Before handling, properly clean the mounting surfaces. Use non-impact pressing tools to install the bearing evenly. Do not apply axial load via the rolling parts during installation. Torque mounting bolts to the prescribed value in a cross-pattern sequence to prevent deformation of the ring. Check axial runout with a dial indicator (4 equally spaced points) after installation. Runout values greater than 5 μm indicate faulty seating or contamination. Compare starting torque with the manufacturer’s requirements. Any discrepancy indicates a preload inconsistency and requires disassembly and re-inspection prior to operation.

YRT 150 High Precision Rotary table bearing is a technically mature, high-value component that directly affects machining precision and equipment dependability. Procurement choices should be based on proven certification, dimensional traceability, and long-term stability of the provider. ATLYC has been producing precision bearings for industrial industries worldwide for the last 15 years. Partnering with an ISO 9001- and IATF 16949-certified manufacturer who can offer complete inspection paperwork protects your production quality and your procurement credibility, whether you are buying a single development unit or setting up a regular supply agreement.
Request a full documentation package from the supplier, including CMM dimensional reports, material hardness certificates (confirming 58–62 HRC), and ISO certification copies. Counterfeit units typically show non-conforming roundness measurements and inconsistent starting torque. Auditing the manufacturer's production facility or requesting a third-party inspection for initial orders adds another layer of confidence.
Standard bulk orders from verified manufacturers typically carry lead times of 20–35 business days, depending on order volume and current production scheduling. ATLYC maintains dedicated capacity for repeat customers, which can compress lead times for established supply agreements.
Yes. Customization options include modified preload levels, alternative precision grades (P4 or P2), special lubrication configurations, and application-specific dimensional adjustments. Discuss your exact load case, speed range, and environmental conditions with the manufacturer's engineering team before finalizing specifications.
The bearing's zero-backlash preload and high tilting rigidity make it well-suited to robotic joint assemblies, automated indexing stations, and precision positioning stages where repeatability and stiffness are critical.
