Causes to decide on Guomai Bearings as your independent needle roller/rolling bearings partner
one. Bearing developing: Guomai has our very own bearing R&D staff and adopts Germany technology. This enables us to offer OEM and ODM service to you.
2. Generation method:We strictly adhere to the 5S manufacturing procedure and obtained ISO9001:2008 high quality administration method certification. In addition to, we launched from abroad ept well-known makes lathes and heat remedy tools, this permits us to supply substantial precision bearings with equivalent quality to ept popular brands this sort of as SKF, ,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Supplies: To make sure the large top quality of bearings, we use higher carbon chrome bearing steel which offers large rigidity, and substantial resistance to abrasive dress in to produce the bearings. Minimal carbon cold rolled metal and low carbon stainless metal is also utilized according to customers’ demands.
four. Quality inspection: All bearings will be strictly analyzed just before packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(pace) measuring instrument,roundness instrument to assure all bearings are competent with the specifications.
five. Lubricants: Appropriate lubricants are utilized to defend the bearings from oxidation or corrosion of areas hence empower our bearings with lengthier lifetime, lower sound and much better large temperature efficiency. Choice of lubricants is typically ruled by the bearing application. Correct decision of substantial quality lubricants could avert metallic to metal contact and perform heat absent from the bearings.
six. Packing: Guomai bearings pay consideration to each and every element in the bearing manufacturing approach. We adopt plastic bag, Kraft paper, thick paper box and cartons to shield the bearings from unexpectable hurt throughout the transportation and warehouse stock.
seven. Manufacturing unit immediate marketing: We are the manufacturing facility and not the distributor or ept agent, so we could offer the very same quality with aggressive value.
What is Needle Roller Bearing?
A needle roller bearing is a unique type of roller bearing which makes use of long, skinny cylindrical rollers loo ept like stitching needles. Rollers of regular roller bearings are only somewhat for a longer time than their diameter, but needle rollers are at minimum four moments more time than their diameter. Like all the other bearings, they are utilized to lessen the friction of rotating surface area.
When compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface spot in contact with the raceways, so they can help a higher radial load but not axial load. They are also thinner, so they require much less clearance amongst the axle and the surrounding construction.
Needle bearings are widely used in ept factors this kind of as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle normally has at least eight needle bearings (four in each U joint) and usually far more if it is particularly lengthy, or operates on steep slopes.
Various kinds of needle bearings are offered in a extensive selection of dimensions and tolerances, for a multitude of applications such as gearboxes, automotive electricity transmission techniques, two and 4 stroke engines, planetary gear sets and air compressors.
Needle roller and cage assemblies are presented in solitary or double row, solid or break up cage, metric and inch dimensions. Single and double row bearings are offered with or without ribs, and with or with no interior rings.
