Factors to decide on Guomai Bearings as your unbiased needle roller/rolling bearings partner
one. Bearing planning: Guomai has our own bearing R&D crew and adopts Germany engineering. This allows us to offer OEM and ODM provider to you.
2. Manufacturing process:We strictly comply with the 5S creation process and acquired ISO9001:2008 high quality management method certificate. Aside from, we launched from abroad ept famous brand names lathes and warmth treatment equipment, this enables us to offer large precision bearings with similar quality to ept well-known brand names these kinds of as SKF, ,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
three. Components: To ensure the high good quality of bearings, we use large carbon chrome bearing metal which gives substantial rigidity, and higher resistance to abrasive dress in to generate the bearings. Lower carbon cold rolled metal and minimal carbon stainless metal is also used in accordance to customers’ specifications.
4. Good quality inspection: All bearings will be strictly analyzed ahead of packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(pace) measuring instrument,roundness instrument to promise all bearings are experienced with the requirements.
five. Lubricants: Ideal lubricants are used to protect the bearings from oxidation or corrosion of elements thus allow our bearings with for a longer time life span, low noise and greater higher temperature performance. Assortment of lubricants is typically governed by the bearing software. Appropriate choice of high top quality lubricants could stop metallic to steel contact and perform heat absent from the bearings.
six. Packing: Guomai bearings pay interest to every detail in the bearing generation process. We undertake plastic bag, Kraft paper, thick paper box and cartons to defend the bearings from unexpectable injury for the duration of the transportation and warehouse stock.
seven. Factory direct advertising: We are the factory and not the distributor or ept agent, so we could give the exact same high quality with aggressive value.
What is Needle Roller Bearing?
A needle roller bearing is a unique type of roller bearing which makes use of prolonged, skinny cylindrical rollers loo ept like stitching needles. Rollers of normal roller bearings are only slightly for a longer time than their diameter, but needle rollers are at the very least 4 occasions for a longer time than their diameter. Like all the other bearings, they are utilized to reduce the friction of rotating surface.
In contrast to ball bearings and other conventional roller bearings, needle bearings have a larger surface area in get in touch with with the raceways, so they can assistance a higher radial load but not axial load. They are also thinner, so they demand less clearance among the axle and the surrounding construction.
Needle bearings are widely used in ept parts this sort of as rocker arm pivots, pumps, compressors, and transmissions. The travel shaft of a rear-wheel travel car typically has at minimum eight needle bearings (4 in every single U joint) and typically far more if it is particularly extended, or operates on steep slopes.
Varied types of needle bearings are obtainable in a extensive variety of dimensions and tolerances, for a multitude of applications such as gearboxes, automotive energy transmission techniques, two and 4 stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are presented in solitary or double row, sound or break up cage, metric and inch measurements. Single and double row bearings are accessible with or with out ribs, and with or with out inner rings.
