Application-Specific Engineering Design to ensure the correct fit, function and high performance of the wheel bearing. BCA supplies premium replacement bearings that meet or exceed the OE specifications. Premium Quality Materials are used for forged steel rings, seals, precision cages, rolling elements and premium grease, to ensure that our customers receive a robust, durable product. Seals are customized for each BCA hub based on application-specific materials and design requirements to minimize the chance of contamination and maximize bearing life. Precision Cage on BCA bearings are designed to keep the rolling elements of the bearing spaced correctly. The cages undergo design verification and production validation testing to ensure high quality. Pre-Lubrication of all BCA wheel bearings with premium grease for your convenience. This is a major advantage so you do not have to worry about grease or seal application.

Product Features:

• Wheel bearing kits include required components for complete bearing replacement
• Cups, cones, and rollers are made from casehardened alloy steel of Bearing Quality to provide superior fatigue life and reliability
• Micro-pitting surface finish increases bearing life in applications with insufficient lubrication
• Austenite strengthening process (AS) is a special heat treatment applied to the rolling elements
• For wheel bearings, BCA utilizes Forged Steel in the inner and outer rings that meets our stringent steel quality specifications to optimize bearing life.
• For taper bearings, BCA utilizes Case Carburized Steel for heavy duty shock loads and longer life.
