Bottom Bracket Wheels Manufacturing

The T47 threaded bottom brackets from Wheels Manufacturing for Sram and Truvativ MTB and road bike GXP cranksets with a 24/22 mm axle, designed for fitting into frames with T47 bottom bracket shells ranging from 68 mm to 100 mm in width

Wheels Enduro ABEC5 angular contact ball bearings:

The Wheels Enduro ABEC5 angular contact full-contact ball bearings are specially designed for use in hubs and bottom brackets. Whereas in standard radial bearings only 3 or 4 balls are loaded simultaneously, in angular contact ball bearings all balls are loaded evenly. This is why this type of bearing is also known as a full-contact bearing. This distributes the applied force across the entire bearing surface, reducing friction and wear. The balls in these Enduro bearings are manufactured to extremely high precision with a tolerance of just 10/1,000,000, twice as precise as standard industrial bearings. Fitted with double silicone seals, double lip seals and heavy-duty grease, these bearings guarantee excellent durability. Enduro bearings are easy to maintain and are interchangeable.

Sram GXP Axle System:

The SRAM GXP crankset system with different axle diameters. The outer diameter of the axle on the drive side is 24 mm and 22 mm on the left side. GXP-compatible bottom brackets are required for this.

T47 threaded bottom bracket shells

The bottom bracket shells have a width of 68 to 132 mm and a 47x1.0 mm thread, with an outer diameter of 47 mm, into which the bearing cups are screwed. Both bearing cups are screwed in the direction of travel. Adjustment to the different shell widths is achieved using the washers included in the scope of delivery.
