Bearing Buddy .198 Chrome Plated Protector offers reliable wheel bearing protection for recreational trailers by continuously lubricating bearings and preventing contamination from water and dirt. Its heavy chrome-plated barrel and stainless steel internal components ensure durability and corrosion resistance. The built-in pressure relief system maintains optimal internal pressure at 3 psi, avoiding overfilling and potential damage. This model does not include a bearing bra but provides long-lasting performance to reduce maintenance and extend bearing life. The BBB1980A and A-SS variants feature a Visual Lubricant Indicator for easy monitoring.
