Causes to decide on Guomai Bearings as your impartial needle roller/rolling bearings partner
1. Bearing planning: Guomai has our very own bearing R&D group and adopts Germany technologies. This allows us to provide OEM and ODM service to you.
2. Manufacturing method:We strictly comply with the 5S creation approach and obtained ISO9001:2008 quality administration technique certification. Apart from, we released from overseas ept well-known brands lathes and heat therapy equipment, this allows us to supply higher precision bearings with similar high quality to ept renowned makes such as SKF, ,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Resources: To make certain the large top quality of bearings, we use high carbon chrome bearing steel which supplies substantial rigidity, and higher resistance to abrasive wear to create the bearings. Minimal carbon chilly rolled steel and minimal carbon stainless steel is also utilised in accordance to customers’ demands.
4. Quality inspection: All bearings will be strictly analyzed ahead of packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(speed) measuring instrument,roundness instrument to ensure all bearings are competent with the requirements.
five. Lubricants: Appropriate lubricants are utilized to defend the bearings from oxidation or corrosion of parts therefore permit our bearings with longer lifetime, reduced noise and far better high temperature functionality. Assortment of lubricants is typically governed by the bearing application. Proper selection of higher high quality lubricants could avoid metal to steel speak to and perform heat absent from the bearings.
six. Packing: Guomai bearings pay out attention to each element in the bearing generation method. We undertake plastic bag, Kraft paper, thick paper box and cartons to protect the bearings from unexpectable harm in the course of the transportation and warehouse inventory.
seven. Manufacturing unit immediate advertising and marketing: We are the manufacturing facility and not the distributor or ept agent, so we could offer the identical good quality with aggressive price tag.
What is Needle Roller Bearing?
A needle roller bearing is a special sort of roller bearing which makes use of prolonged, slim cylindrical rollers loo ept like stitching needles. Rollers of common roller bearings are only slightly for a longer time than their diameter, but needle rollers are at the very least four occasions for a longer time than their diameter. Like all the other bearings, they are used to lessen the friction of rotating surface.
In contrast to ball bearings and other conventional roller bearings, needle bearings have a larger surface location in speak to with the raceways, so they can assist a higher radial load but not axial load. They are also thinner, so they require less clearance in between the axle and the encompassing composition.
Needle bearings are widely used in ept elements such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive car usually has at least eight needle bearings (4 in every U joint) and usually a lot more if it is specifically long, or operates on steep slopes.
Diverse sorts of needle bearings are available in a extensive variety of measurements and tolerances, for a multitude of applications such as gearboxes, automotive energy transmission programs, two and 4 stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are supplied in single or double row, strong or split cage, metric and inch measurements. One and double row bearings are offered with or without having ribs, and with or without having interior rings.
