Shell type needle roller bearing HK0810

Shell Type Needle Roller Bearing HK0810 - High Performance Radial Load Solution

The Shell type needle roller bearing HK0810 represents an advanced engineering solution for applications requiring maximum radial load capacity within minimal space constraints. This precision-engineered drawn cup needle roller bearing features an 8mm inner diameter, 12mm outer diameter, and 10mm width configuration, making it ideal for compact mechanical assemblies. Manufacturing professionals and engineers choose this bearing for its exceptional space efficiency and reliable performance in demanding industrial applications. The HK0810's unique shell construction eliminates the need for separate outer rings while providing superior load distribution across the needle roller assembly.

Product Overview

The HK0810 utilizes a thin-walled, deep-drawn outer shell made from precision-hardened steel. This shell serves as the raceway for the needle roller and cage assembly. The bearing operates through direct contact between the needle rollers and a hardened shaft surface, eliminating the inner ring requirement.

Design Features and Engineering Benefits

Space-Optimized Construction

The shell design provides maximum radial load capacity within an extremely compact cross-section. This allows for larger shaft diameters in smaller housing bores, optimizing space utilization in tight mechanical assemblies.

Press-Fit Installation System

The bearing installs via interference fit in the housing bore. This eliminates axial location devices such as snap rings, simplifying housing design and reducing production costs for high-volume manufacturing.

Hardened Steel Components

The outer shell features ST14 steel construction with precision hardening. Needle rollers manufactured from GCr15 bearing steel achieve HRC 60-64 hardness, ensuring excellent wear resistance and extended service life.

Lightweight Cage Design

Available with steel stamped or PA66 polymer cages, the bearing maintains low rotational inertia while providing reliable roller guidance at high speeds.

Primary Applications

Automotive Components

The Shell type needle roller bearing HK0810 excels in automotive starter motors and throttle valve assemblies. It handles high-frequency oscillation and thermal stress in near-engine environments while retaining lubrication effectively.

Industrial Power Tools

Professional-grade electric drills and grinding machines utilize this bearing in gear reduction stages. It supports high rotational speeds while withstanding shock loads and vibration during heavy-duty operations.

Precision Machinery

Fan motor shafts and printer roller assemblies benefit from the bearing's smooth operation and compact design. The low-profile construction enables efficient mechanical layouts in space-constrained equipment.

Garden and Agricultural Equipment

String trimmers and portable machinery rely on the HK0810 in clutch drums and drive shafts. The bearing maintains performance in debris-heavy environments when properly sealed.

Installation Guidelines

Housing Requirements

Prepare housing bores to N6 or N7 tolerance class for steel housings. Ensure proper bore alignment and surface finish to prevent installation damage.

Press-Fit Procedure

Use dedicated pressing mandrels that contact the stamped face of the outer ring. Never apply direct hammer blows to the bearing. Maintain controlled pressure during installation.

Shaft Specifications

The shaft must be ground and hardened to HRC 58-64 with surface roughness of Ra ≤ 0.2 µm. Since the bearing has no inner ring, the shaft serves as the inner raceway.

Performance Characteristics

Load Capacity

With a dynamic load rating of approximately 3.8 kN and static load rating of 4.45 kN, the bearing handles substantial radial loads despite its compact size.

Speed Capability

The lightweight design enables operation up to 28,000 RPM with proper oil lubrication, making it suitable for high-speed applications.

Durability Features

The exactness fabricating prepare guarantees steady execution beneath requesting conditions. The solidified components stand up to wear and keep up dimensional steadiness all through the benefit life.

Quality Assurance

Our fabricating handle joins three-level quality control counting crude fabric review, in-process observing, and comprehensive wrapped up item testing. Each bearing experiences confirmation of 12 center execution markers counting vibration testing and life cycle validation.

The item accomplishes over 99.9% capability rate, guaranteeing solid execution over assorted mechanical applications.
