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:does a 1991 mazda 626 have front wheel bearings?: Of course it does. ALL wheels have bearings, no matter what make or model of vehicle you have. Even wheelbarrows need bearings in the wheel. The possible exceptions are the single ball type wheels that have a hollow sleeve in the centre as opposed to a roller or pin type bearing as is the norm. Hope this helps.

Q:I've been searching my textbook and cannot find the types of bearings that are in a manual transmission. I need to know what types are in this type of transmission and when they are active (not being used). I know there's the pocket (pilot) bearing, but there are more. Can someone please help me figure this out? It's much appreciated. Thanks.: Mainshaft bearings, countershaft bearings, input shaft bearing.....some are tapered, some are roller,some are needle bearings.........

Q:how can i loosen the nuts that hold the bearings in on my hyper bike co bike?: Which bearings?. Are they the wheel bearings, the crank bearings, the headset bearings, or the pedal bearings?

Q:My 2000 4x4 Lifted Ford Excursion has a clicking noise when I am driving, on the front driver side. I can take my foot off the gas an it is still there no matter the speed. I am thinking it is a bad Hub/Bearing? How would I know for SURE that is what it is? Any tips on what to look for if I jack it up? Thanks.: Jack up the vehicle and check the bearing for play from top to bottom....

Q:how do theymake steel ball bearings so perfectly round and of the same size?: check out National Geographic channel or discovery channel in your area. Got a progran called How it's made. Shows 4 different things each time it's aired and it airs couple times a day. I know for a fact they had ball bearings on there once. Done with a machine. May be on one of their websites too.

Q:Give a detailed procedure of maintenance of electric motor bearings and the effects of overgreasing?: Motor manufacturers have recommendations which are specific to the device and service category (ambient temperature, load, duty cycle, air quality, dust, particulates, etc.). These vary for journal, roller, and radial ball bearings. In the case of electric motor bearings; cleanliness and free air circulation for cooling are critical. Ball bearing are generally sealed or shielded, and permanently greased. In cases where they are being restored as they approach the end of design basis service life; they can be cleaned in an oil bath (not to exceed 100C), rinsed in solvent, and regreased to ?-? of the free volume. Excess grease is universally regarded as destructive. Over greasing is said by motor manufacturers to create overheating which boils off volatiles and changes the properties of the grease. The vapors from condensation deposit nearby trapping dust, blocking air flow, and exacerbating overheating. Lubricant manufacturers cite degradation of lubricant due to shear.

Q:buying my first skateboard.: the bearings are what make the wheels move on the trucks and it holds the wheels to the trucks .. its the thing inside the wheels and it can be any color like mine are red

Q:Which one is the better of the two? im looking mostly for speed and for them to be waterproof: you shouldn't be riding in the water and that will ruin all bearings and make them rust. The Bones are faster but if you are going to ruin 100+ $$$ bearings just get Sector 9 greaseball bearings.
