Compact BK4520 RICH Closed-End Needle Roller Bearing – 45 x 52 x 20 mm
Boost the performance of your compact mechanical systems with the efficient and robust BK4520 RICH closed-end needle roller bearing. Engineered with precision, this bearing boasts an integrated closed end that functions as a seal—preventing contaminants and retaining lubricant. This results in reduced wear and a longer working life.
With its compact dimensions (45 mm inner diameter × 52 mm outer diameter × 20 mm width), it's ideally suited for blind-end housings or scenarios where a through-hole isn't feasible. Despite its small stature, it provides exceptional radial load support, making it a trusted solution for gearboxes, automotive parts, power tools, and precision instruments.
Produced by RICH under stringent quality control in China, the BK4520 delivers consistent, high-end performance even under challenging conditions. Its sealed-end design guarantees quiet functionality, minimal maintenance, and superior system protection.
