Applications of NA4904 bearing 20*37*17mm NA4904 needle roller bearing
NA4904 bearing 20*37*17mm NA4904 needle roller bearing is used in the design of the bearing shaft for the bearing raceway, which has certain requirements on the hardness of the bearing; or with the IR standard inner ring for the insert processing, there is no requirement for the shaft hardness, and the structure will be more compact.
FAQ of NA4904 bearing 20*37*17mm NA4904 needle roller bearing:
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.
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 NA4904 bearing 20*37*17mm NA4904 needle roller bearing?
(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 NA4904 bearing 20*37*17mm NA4904 needle roller bearing?
It can cover almost all mechanical industries, including robotic systems, lathes, tools, automobiles, large equipment, and so on.
A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
A: Sample needs 3-7 days, mass production time needs 3-4 weeks.
A: We accept T/T, PAYPAL or Western Union, credit card.
