61909 Deep Groove Open Ball Bearing - Technical Specifications & Applications

Product Overview

The 61909 Deep Groove Open Ball Bearing is a precision-engineered, thin-section bearing designed for applications requiring compact dimensions and high-speed operation. With standardized dimensions of 45mm bore, 68mm outer diameter, and 12mm width, this bearing delivers reliable radial and axial load support in space-constrained installations. The open configuration eliminates contact seals, reducing friction and enabling superior heat dissipation for demanding industrial applications. At Luoyang Auto Bearing Co., Ltd., we manufacture this bearing to ISO standards using premium GCr15 bearing steel and precision grinding technology.

Design Features & Working Principle

Auxiliary Configuration

The bearing comprises of four fundamental components: internal ring, external ring, ball complement, and cage gathering. The profound groove raceway plan gives ideal contact geometry between steel balls and rings. This arrangement empowers the bearing to bolster combined spiral and hub loads simultaneously.

Load Dispersion Mechanism

The point contact between balls and raceways makes negligible grinding amid operation. The profound groove geometry permits for higher pivotal stack capacity compared to shallow groove plans. Stack conveyance happens equitably over all rolling components through the cage dividing system.

Performance Advantages

Low Contact Operation: The open plan kills seal drag, decreasing beginning torque and operational contact. This characteristic empowers higher rotational speeds and progressed vitality efficiency.

Enhanced Warm Dissemination: Without shields or seals, grease streams unreservedly through the bearing, carrying absent produced warm. This warm administration capability amplifies bearing life in high-speed applications.

Precision Execution: Fabricating resiliences guarantee negligible spiral and hub runout. The bearing keeps up dimensional soundness beneath changing stack conditions.

Application fields

Primary Applications

Industrial Motors

The 61909 Deep Groove Open Ball Bearing serves as a standard component in electric motors ranging from 5-50 HP. Its thin section design allows motor manufacturers to reduce housing weight while maintaining shaft rigidity.

General Mechanical Transmission

You will find this bearing in gearboxes, conveyor systems, and machine tool spindles. The open configuration supports oil bath lubrication systems common in industrial transmissions.

Automotive Components

Applications include transmission assemblies, differential units, and auxiliary drive systems. The bearing's compact profile fits modern vehicle packaging constraints while handling operational speeds up to 13,000 RPM.

Precision Equipment

Laboratory instruments, textile machinery, and packaging equipment benefit from the bearing's low noise characteristics and smooth operation.

Production equipment

Quality Control & Manufacturing

Our manufacturing process incorporates three-stage quality verification: raw material inspection, in-process monitoring, and final product testing. Each bearing undergoes vibration analysis, dimensional verification, and load testing before shipment.

The heat treatment process achieves 60-64 HRC hardness for optimal wear resistance. Precision grinding operations maintain surface finish requirements for smooth operation and extended service life.

Installation & Maintenance Guidelines

Mounting Procedures

Ensure clean gathering conditions and appropriate shaft/housing fits. Utilize mechanical or water powered mounting devices to anticipate bearing harm amid establishment. Confirm that mounting strengths apply as it were to the ring being fitted.

Lubrication Requirements

The open plan requires outside oil frameworks. Oil shower or circulation frameworks give ideal execution for high-speed applications. Oil grease suits direct speed and temperature conditions.

Operational Monitoring

Monitor working temperature, vibration levels, and commotion characteristics. Supplant grease agreeing to working conditions and producer suggestions.

Supply Chain & Delivery

We maintain inventory of standard 61909 Deep Groove Open Ball Bearing units for 48-hour delivery on regular orders. Our integrated supply network supports both standard specifications and customized variants for special applications.
