Reasons to choose Guomai Bearings as your independent needle roller/rolling bearings partner
1. Bearing developing: Guomai has our own bearing R&D crew and adopts Germany engineering. This permits us to give OEM and ODM support to you.
2. Generation method:We strictly stick to the 5S creation method and obtained ISO9001:2008 good quality administration program certification. Apart from, we released from overseas ept famous brand names lathes and heat therapy equipment, this enables us to offer higher precision bearings with similar good quality to ept popular makes this sort of as SKF, ,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Resources: To guarantee the large good quality of bearings, we use large carbon chrome bearing steel which supplies substantial rigidity, and higher resistance to abrasive dress in to generate the bearings. Low carbon cold rolled metal and low carbon stainless steel is also utilised according to customers’ requirements.
four. High quality inspection: All bearings will be strictly tested before packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(speed) measuring instrument,roundness instrument to promise all bearings are competent with the requirements.
five. Lubricants: Suitable lubricants are utilized to protect the bearings from oxidation or corrosion of parts thus enable our bearings with longer life span, lower noise and much better substantial temperature overall performance. Selection of lubricants is normally ruled by the bearing software. Proper option of higher top quality lubricants could stop metallic to steel contact and perform heat absent from the bearings.
six. Packing: Guomai bearings pay attention to each depth in the bearing production method. We undertake plastic bag, Kraft paper, thick paper box and cartons to protect the bearings from unexpectable damage in the course of the transportation and warehouse inventory.
seven. Manufacturing facility immediate marketing: We are the manufacturing unit and not the distributor or ept agent, so we could supply the very same quality with aggressive cost.
What is Needle Roller Bearing?
A needle roller bearing is a special variety of roller bearing which employs long, slender cylindrical rollers loo ept like stitching needles. Rollers of regular roller bearings are only a bit for a longer time than their diameter, but needle rollers are at the very least 4 instances for a longer time than their diameter. Like all the other bearings, they are employed to reduce the friction of rotating area.
In comparison to ball bearings and other conventional roller bearings, needle bearings have a larger surface area in speak to with the raceways, so they can assist a increased radial load but not axial load. They are also thinner, so they need considerably less clearance among the axle and the bordering structure.
Needle bearings are widely used in ept components such as rocker arm pivots, pumps, compressors, and transmissions. The generate shaft of a rear-wheel drive car normally has at minimum eight needle bearings (four in every single U joint) and frequently a lot more if it is specifically lengthy, or operates on steep slopes.
Various kinds of needle bearings are offered in a vast selection of sizes 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 offered in solitary or double row, reliable or split cage, metric and inch dimensions. Single and double row bearings are obtainable with or with no ribs, and with or without having interior rings.
