Q:How often should a cyclist grease their wheel bearings if riding 100 miles a week?
If the bearings can be serviced, about once per year. If they are sealed bearings, you replace them when they start to fail. You can also disassemble and service your hubs yearly. How this is done depends on the specific hubs you have
Q:Needle roller bearings are how to process the needle, so smooth finish?
The process of needle: blank forming, deburring, heat treatment, coarse and fine grinding, end rolling surface, super finishing rolling surface polishing or sawdust.For flat head or taper head needle roller, such as blank forming, it is difficult to guarantee the length and size tolerance, and the grinding double end process can be increased. If the convex generatrix rolling surface is needed, it can be carried out directly in the process of super finishing, rolling or channeling.Needle roller bearing (needlebearing) is a roller bearing with cylindrical roller, relative to its diameter, the roller is thin and long. This roller is called needle roller. Although it has a small section, the load bearing capacity of the bearing is still high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, the minimum diameter of the diameter and load capacity and other types of bearings, bearing the same, especially for the radial installation size limited. According to the use of different occasions, can choose the inner ring of the bearing or needle roller and cage assembly, the shaft neck surface and the surface of shell holes matched with a bearing directly as the bearing inner and outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness the machining precision and the surface quality of bearing ring raceway and similar. This kind of bearing can only bear radial load. The needle roller bearing for stamping outer ring is needle roller bearing with thin stamping forming outer ring.
Q:Trouble locating bearing for wheel of 2002 Hyundai Sonata. Do Hyundai bearings come with numbers on them?
call parts at dealerships for hyundai
Q:Rear wheel bearings - how important to replace as a pair?
Just the faulty side. Any of the others will clearly tell you when they want to be replaced. The other could go next week or 25k from now. If the fronts did not go first, then are you sure it needs replacing? It should have a tell-tale whrrrrring sound when the wheel is spun off the ground. But the acid test is it gets louder when you swerve (carefully). Louder on a right swerve means left bearing history. Louder on left swerve means right bearing history. 45mph in light traffic Except for odd-ball occurrences, the very first thing a bad bearing should tell you is your car may no longer be worth fixing. That's because all of the other fixes needed at high miles, and soon coming, cost far more than the value of additional miles. Depending on the make (like Subaru) and the use (like gravel truck) there are exceptions to that way of thinking.
