Tolerance Standards: Inner diameter tolerance 0/-0.01 mm, outer diameter tolerance 0/+0.013 mm, width tolerance ±0.1 mm, surface roughness Ra ≤ 0.4 μm
Lubrication and Sealing: Pre-filled lithium-based extreme pressure grease, double-sided NBR seal, dustproof and waterproof, suitable for dusty and humid conditions, extending lubrication intervals.
Structure and Core Features:
Deep groove ball structure: Can withstand radial loads and bidirectional small axial loads simultaneously, suitable for high-speed rotation scenarios, reducing friction loss and improving transmission efficiency.

Double-sided sealing design: The NBR sealing ring is combined with a metal skeleton to effectively prevent dust and moisture intrusion, prevent grease leakage, suitable for harsh working conditions in engineering machinery, and reduce maintenance frequency.

High-strength material: GCr15 chromium steel, quenched, tempered, and precision ground, possesses high hardness and high wear resistance. The cage is made of reinforced nylon 66, lightweight and with good toughness, suitable for high-frequency vibration environments.

C3 Clearance Specification: Provides a reasonable radial clearance to accommodate temperature changes and assembly errors, preventing jamming during operation and ensuring long-term stable operation.

Compatible Models and Application Scenarios

Compatible Equipment: CAT 307E2/308E2 excavators, 262D/272D skid steer loaders, C4.4/C6.6 engines, 906M/907M loaders, and other small to medium-sized equipment.

Core Applications: Used in hydraulic pump spindles, gearbox output shafts, fan drive shafts, and auxiliary supports for rotary motors, bearing radial loads under high-speed rotation, ensuring accurate component positioning and stable transmission, suitable for medium to light load, high-speed operating conditions.
