Causes to decide on Guomai Bearings as your unbiased needle roller/rolling bearings partner
one. Bearing designing: Guomai has our personal bearing R&D staff and adopts Germany engineering. This enables us to offer OEM and ODM provider to you.
two. Production method:We strictly follow the 5S generation approach and obtained ISO9001:2008 good quality administration technique certification. Apart from, we introduced from overseas ept famous brand names lathes and heat treatment products, this permits us to supply large precision bearings with related quality to ept renowned makes these kinds of as SKF, ,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Materials: To ensure the substantial good quality of bearings, we use high carbon chrome bearing steel which gives substantial rigidity, and higher resistance to abrasive wear to produce the bearings. Minimal carbon cold rolled metal and minimal carbon stainless steel is also employed in accordance to customers’ demands.
four. Good quality inspection: All bearings will be strictly examined before packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(speed) measuring instrument,roundness instrument to ensure all bearings are qualified with the specifications.
five. Lubricants: Suitable lubricants are used to shield the bearings from oxidation or corrosion of areas thus allow our bearings with for a longer time life span, low sound and far better large temperature functionality. Variety of lubricants is usually ruled by the bearing software. Proper decision of substantial quality lubricants could prevent steel to metal make contact with and carry out heat away from the bearings.
six. Packing: Guomai bearings spend interest to each and every depth in the bearing creation process. We undertake plastic bag, Kraft paper, thick paper box and cartons to shield the bearings from unexpectable hurt during the transportation and warehouse inventory.
seven. Factory direct advertising: We are the manufacturing facility and not the distributor or ept agent, so we could give the very same high quality with competitive value.
What is Needle Roller Bearing?
A needle roller bearing is a specific variety of roller bearing which employs lengthy, slender cylindrical rollers loo ept like sewing needles. Rollers of common roller bearings are only a bit more time than their diameter, but needle rollers are at least 4 occasions longer than their diameter. Like all the other bearings, they are employed to lessen the friction of rotating area.
When compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface area in make contact with with the raceways, so they can support a increased radial load but not axial load. They are also thinner, so they demand significantly less clearance amongst the axle and the encompassing composition.
Needle bearings are widely used in ept components such as rocker arm pivots, pumps, compressors, and transmissions. The push shaft of a rear-wheel travel car normally has at least eight needle bearings (four in each U joint) and frequently more if it is specifically extended, or operates on steep slopes.
Varied kinds of needle bearings are accessible in a vast variety of measurements and tolerances, for a multitude of applications such as gearboxes, automotive electricity transmission techniques, two and 4 stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are supplied in solitary or double row, solid or break up cage, metric and inch measurements. Solitary and double row bearings are accessible with or without ribs, and with or with out internal rings.
