BLACKBEARING UB-63803-MAX Bearing – 63803-2RS (17 × 26 × 7 mm)
EAN: 3760290196575
Part Number: UB-63803-MAX
Brand: BLACKBEARING
Type: MAX bearing, 63803-2RS
The BLACKBEARING UB-63803-MAX is a MAX bearing specifically designed for bicycle frame pivot points and suspension systems. The MAX design is developed to handle the higher radial loads and demanding operating conditions typically encountered at suspension pivot points, compared with standard industrial bearings.
At frame pivot points, bearings are subjected to significant loads while still being required to operate precisely and with minimal play. MAX bearings are designed with these specific requirements in mind, making them particularly suitable for MTB frames, rear suspension systems, and other bicycle frame pivot applications.
The 2RS double rubber seal helps prevent dust, water, and dirt from entering the bearing, which is especially important for bicycle suspension pivot points exposed to mud, moisture, and other contaminants.

IN PRACTICE
BLACKBEARING MAX bearings are not simply general-purpose industrial bearings; their design is specifically intended for the loads and operating conditions encountered at bicycle frame pivot points. Bearings in these locations must withstand significant loads while maintaining precise, smooth operation with minimal play.
The MAX design makes these bearings particularly suitable for full-suspension MTB bicycles, where pivot bearings are exposed to substantial loads and repeated movement. Using the correct MAX bearing helps maintain precise suspension operation, minimize unwanted play, and provide reliable long-term bearing performance.
The 2RS sealing system provides additional protection against water and contaminants, making the bearing well suited to frame pivot points that are regularly exposed to wet, muddy, and dusty riding conditions.
