freewheel bearing and na needle bearing

Shanghai Metal Corporation is experienced manufacturer of bearings in China; all the production will be proceed accordingly to ISO9001:2008 strictly, only best quality bearing steel will be used for the manufacturing, all the raw material must be inspected by spectrograph before production; With more than 60 sets of advanced CNC production lines, 78 processing procedures and strict inspection, we ensure 100% zero defect quality.

General diamensions:
Inner Diameter:25mm~100mm  Outer Diameter:50mm~160mm
Width:15mm~40 mm
Application:
It is mainly used as vehicle transmission, automobile reducer assembly, agricultural machinery, and so on.
Key Specifications/Special Features:
•Roller raceway surface of cylindrical roller bearings is line contact so bearing has high carrying radial load capacity applicable to carrying heavy load and shock load
•Easy to high accuracy processing applicable to high rate rotary
•Inner and outer ring are separable convenient for mounting and dismounting
•Single row cylindrical roller bearing
•Taper NU and type NF can carry certain extent one-way axial load
•Type NUP and NH can carry certain extent both-way axial load
•Main dimensions of type E cylindrical roller bearing coordinate with standard and through modifying interior specification to increase nominal load
•Double row cylindrical roller bearing with cylindrical hole type and tapered hole type
•Tapered bore bearing can get needed internal clearance by self-aligning depth of thrusting in
•Besides there are bearing whole outer ring with oil hole and tank it is nominal type code has post position assistant code W
•Type bearing has strong fixity resisting reversal load, mainly applicable to chief shaft of machine tool.

General diamensions:

Key Specifications/Special Features
•Used in automobile
•Usually separated
•S rolling mill and metallurgical plastic machinery
•Designed in such a way that cone apexes of inner ring race way, outer ring way intersects at one point of central line, beside metric series products there are inch series products, which are applicable for heavy and impact load
•Can bear simultaneously radial load and single row axial load, when carrying radial load
•Creates axial thrust load thus two bearings are configured or combined face to face back to back, according to the contact angle difference, classified into three types (small/medium/big cone angle)
•Used for construction/agriculture machinery, spindle, gear box and automotive manufacturing
Material: chrome steel (GCR15)
Cage: stamped steel
