FAQ:
Q: What kind of bearings you supplied?
A: We supply all specification of bearings: deep groove ball bearings —-
tapered roller bearings—– cylindrical roller bearings —-Spherical Roller Bearings
—– angular contact bearings – – thrust roller bearings —-thrust ball?bearings—-
spherical bearings -needle roller bearings—-pillow block bearings—-sliding guide bearings
—-wheel hub bearings and high-precision low-noise high-speed operation of special bearings.
We also agent and supply all world famous brands of bearings: SKF bearings, NTN bearings,
NSK bearings, NACHI bearings, TIMKEN bearings, KOYO bearings, IKO bearings, INA bearings,
NMB bearings, BONES REDS bearings…
Non-standard bearings can be produced according to your drawing in our factory.
Q: When selecting bearings, what should we need to consider?
A: The precision of the bearings (dimension tolerance, loading rate), internal
clearance and hardness under heat treatment, the structure of cage and material.
Q: The advantage of bearings?
A:
(1) reduce friction and wear.
To prevent metal contact and reduce friction and wear in the contact part of the bearing ring,
rolling body, and maintainer.
(2) prolong fatigue life.
The rolling fatigue life of the bearing, in the rotation, the rolling contact surface lubrication good,
then extended. Conversely, the oil viscosity is low, the lubricating film thickness is not good,
then shortened.
(3) exhaust friction heat and cooling.
The circulation to oil method can be used to exhaust the heat generated by friction, or from external
heat, cooling. Prevent the bearing from overheating and prevent the lubricating oil from aging itself.
Q: Application area of bearings?
It can cover almost all mechanical industries, including robotic systems, lathes, tools, automobiles, large equipment, and so on.
Q: Can I have a sample order?
A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
Q: What about the lead time?
A: Sample needs 3-7 days, mass production time needs 3-4 weeks.
Q: What is your payment method?
A: We accept T/T, PAYPAL or Western Union, credit card.
