7011CD P4A SKF Angular contact ball bearing 7011CD/P4A .
Angular conta ct ball bearing. Concept. Angular contact ball bearings can bear radial load and axial load at the same time. The bearing can work at a higher speed. The larger the contact angle, the higher the axial bearing capacity. It is usually take 15 degrees contact angle at the high precision and high speed.

A Look Inside a "Made In The USA" Bearing - Bike Test Revie
A Look Inside a 'Made In the USA' The Parts Shoppe (TPS) 6806 Bicycle BB30 Bottom Bracket Bearing As an engineer by trade, I am always looking at best ways to make the bicycle faster. It took about a year, but I was eventually able to find a Chinese bearing manufacturer who produces fairly decent hybrid-ceramic bearings. Most Chinese companies who claim to be manufacturers are actually ...
Angular Contact Bearings - Motion Industri
Internal clearance is how much the bearing's rolling elements move within the raceway before the bearing is mounted to a shaft. A greater internal clearance means there is more space, or looseness, within the bearing. Internal clearance is most commonly expressed with the letter C followed by a number, with C0 being standard clearance.

SKF single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation.
