Bicycles bearing manufacturers to teach you how to identify good or bad and how bicycle bearings in the shaft removed.

Bicycle bearings how to identify good or bad

Bicycle bearings for Palin, it's a foreign Word, the bike a little more technically known as deep groove ball bearings, thrust bearings is mainly used for the bike, but higher prices of deep groove ball bearings, with relatively few on the bike.

Rolling bearings at work, inner sleeve and shaft tightly, turned along with the axis, and coat on the fixed bearing. Axis twist at work rejected, torque, load bearing parts under axial reaction forces, and the role of pressure. Rolling bearings, jackets and rolling elements are in working under alternating stress. Scroll and the inner, jacket and cage are sliding, friction, wear, friction and surface temperatures will rise in their work.

Bicycle rear wheel bearing outer ring is rotated, the equivalent of double row angular contact ball bearings. Rear wheel bearings are mainly under rotating load under predominantly fixed front wheel bearing loads. Bicycle chain drive, pedal-driven front sprockets, transmission to the rear sprocket, chain a torque to the rear wheels, driving the rear wheels rotate, rear wheel with the bearing outer ring with fixed, steel ball rotation and revolution, inner circle still. A torque to the front wheels forward, rotate the front wheel bearings and front wheel, ball rotation and revolution, walking forward. Corner, front wheel bearing one-side tilt under torque.

Really high-end bike without bearings, bicycle bearings once under pressure, bearing a certain degree of plastic deformation, reaction to the driver feels is "missed" it appears not smooth feeling. Bike bearing the real good or bad, depends on its design and process technology, and measurement of a bike bearing the most is to see the five running accuracy of the bearing.

Bicycle bearings in the shaft removal method:

1. Remove left and right side crank 2 Hexagon bolts.

2. the use of special tools codes, crank removal 2.

3. Remove left blocking the shaft in the Bowl (five-port on the left side of the frame), left out of Bowl is plastic, split attention said, attention: loose counterclockwise.

4. Remove shaft on the right side of the frame, right side retaining Bowl here is with the shaft in one of fact, this is the axis of the shell, attention: loose clockwise.

5. shaft after removal to remove the pig down the mouth, should be in the shaft on the left side of the structure from the inside to the outside is here: marbles, snout, gaskets, fixing screws, dust-proof cover.

Note: disassembly sequence is dust-proof cover fixing screw, washer, snout, pool, thread is loose left-right tight.

6. remove the shaft connecting rod, with special attention to marbles off the record number.

7. the shaft in the left end of the shell wall has 2 different marbles fixed dust aprons, pay attention to the size and location of records and then removed.
