3. Components: To ensure the high quality of bearings, we use substantial carbon chrome bearing steel which offers large rigidity, and large resistance to abrasive use to produce the bearings. Lower carbon chilly rolled metal and lower carbon stainless metal is also employed in accordance to customers’ demands.
4. Good quality inspection: All bearings will be strictly tested before packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(pace) measuring instrument,roundness instrument to assure all bearings are qualified with the requirements.
five. Lubricants: Suited lubricants are utilised to protect the bearings from oxidation or corrosion of parts therefore empower our bearings with lengthier lifetime, minimal noise and much better large temperature efficiency. Variety of lubricants is generally ruled by the bearing software. Correct decision of high quality lubricants could avert metallic to metal contact and carry out warmth away from the bearings.
6. Packing: Guomai bearings spend interest to every single element in the bearing manufacturing method. We adopt plastic bag, Kraft paper, thick paper box and cartons to safeguard the bearings from unexpectable hurt in the course of the transportation and warehouse stock.

What is Needle Roller Bearing?
A needle roller bearing is a special sort of roller bearing which employs prolonged, slender cylindrical rollers loo ept like sewing needles. Rollers of normal roller bearings are only somewhat lengthier than their diameter, but needle rollers are at least 4 occasions more time than their diameter. Like all the other bearings, they are utilized to minimize the friction of rotating surface.
Compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface location in get in touch with with the raceways, so they can support a greater radial load but not axial load. They are also thinner, so they demand considerably less clearance between the axle and the encompassing 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 travel automobile generally has at minimum 8 needle bearings (4 in each U joint) and frequently more if it is specifically long, or operates on steep slopes.
Varied varieties of needle bearings are offered in a extensive assortment of measurements and tolerances, for a multitude of applications such as gearboxes, automotive electricity transmission programs, two and 4 stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are supplied in solitary or double row, sound or break up cage, metric and inch sizes. Solitary and double row bearings are offered with or with no ribs, and with or with no interior rings.
