Product Description

Product Overview

The 50BA0751 High-Precision Automotive Angular Contact Ball Bearing is engineered specifically for vehicle powertrain and drive systems, offering superior capability in handling simultaneously acting radial and axial loads. It is widely used in high-performance automotive gearboxes, transaxles, and precision rotating assemblies where extreme running accuracy, thermal stability, and optimized preloading are strictly required.

Key Advantages

Optimized Automotive Contact Geometry: Designed with a specific contact angle to deliver high axial rigidity and stable rolling behavior.
Exceptional High-Speed Capability: Low friction coefficient minimizes heat buildup, allowing the bearing to operate efficiently at extreme RPMs.
Premium Ultra-Clean GCr15 Steel: Advanced hardening treatments prevent structural cracking and dramatically extend wear life under heavy torque stress.
Ultra-Precision Tolerances (P6/P5): Tight dimensional control ensures smooth shifting, quiet operation, and minimum powertrain vibration.
Compact Thin-Section Design: Offers high load-carrying capacity within a streamlined 12mm width, ideal for space-critical transmission housings.

Frequently Asked Questions

Q1: Can the 50BA0751 single-row angular contact bearing support bi-directional axial loads?

A single row angular contact ball bearing can only support axial loads acting in one direction. For applications requiring bi-directional axial load support, these bearings are typically mounted in pairs (back-to-back or face-to-face arrangements).

Q2: Does your factory supply the 50BA0751 with specialized grease or open for transmission oil?

Our standard 50BA0751 model is supplied as an open-type configuration, which is perfect for continuous oil-lubricated environments like automotive gearboxes. However, custom pre-greased variants can be manufactured upon request.

Q3: What automotive quality certificates does your factory hold?

Our manufacturing facilities are fully certified under IATF 16949 (the global automotive quality management standard) as well as ISO 9001:2015, ensuring complete compliance with rigorous Tier-1 automotive criteria.

Q4: How do you package the bearings to ensure they remain rust-free during ocean transit?

Every bearing undergoes an anti-rust oil dip, is vacuum-sealed in a heavy-duty plastic bag, packaged into an individual neutral box, and packed onto reinforced, moisture-wrapped plywood pallets.
