ABEC 3 bearings from PQB Bearings feature 10th-degree chrome steel balls that are twice as round as the industry standard, and manufactured to the highest standard. The treads are made of a 52100 carbon chrome steel alloy that is vacuum-generated and then hardened for extra strength and durability. A high-gloss polish ensures precision and low noise.
PQB full bearings are characterised by a 35 to 40 % higher load capacity than standard radial bearings. For 20 years PQB Bearings has been manufacturing them specifically for use on mountain bike shocks. As its name indicates, Full bearings are fitted with the maximum possible number of balls. The grooves in the races are deeper to accommodate the multiple lateral turning forces at the MTB rear pivot.
This is a High Quality ball bearing - Deep Groove - Radial Bearing 6907 ZZ ABEC 3 (35 x 55 x 10mm) ABEC 3 rate Designed to use for markets bearing, transmissions, gearboxes, belts, chain and related products, and offers a spectrum of powertrain rebuild and repair services.
