INA Bolt Curve Roller Bearing
2020-04-27 11:24 Author:admin Click:
INA bolt-shaped curved rollers are generally full-roller structures. The bolt shaft raceway is quenched. To avoid stress concentration, the outer surface of the thick-walled outer ring of the roller is curved. The outer ring has two integral ribs, which are guided axially by rollers. The head of the bolt shaft and the press-fit side ring provide axial support for the outer ring through rollers.Need INA Bolt Curve Roller Bearing INA KR5202 2RS E55EB
INA Curved roller bearings are suitable for heavier radial loads. Since the outer ring is axially guided by rollers, the bearings can also withstand heavy axial loads, allowing relatively high-speed operation. However, because it is full of rollers, grease needs to be replenished frequently, and lubricant can be added through the holes on both ends of the mandrel and the mandrel body.
Classification
1) Basic NUKR series
The NUKR series of bolt shaft curve rollers is a full-fill double-row cylindrical roller structure.
2) Eccentric sleeve NUKRE series
The bolt shaft curve rollers NUKRE series and NUKR series are similarly full-filled double-row cylindrical roller structure, the only difference is that the NUKRE series has an eccentric sleeve on the bolt shaft.
3) Double raceway PWKR series
The PWKR series of bolt shaft curve rollers are similar to the NUKR series, and they are full-filled double-row cylindrical roller structures. The only difference is that the outer ring of PWKR is double-roller, and the two rows of rollers are separated.
4) NUKRA series with side rollers
NUKRA series and NUKR series are similar in appearance, the difference is that NUKRA is a double-headed bolt, and a side roller is added to the end of the bolt shaft, which leads to structural changes. NUKRA is a single-row full-fill cylindrical roller structure.
5) KR series
KR series curved roller bearings are needle roller cage assembly bearings. The outer ring is axially guided through the ribs on the bolts and the ribs fixed on the bolts, which can withstand heavy loads and medium speeds. Since there is more grease storage space inside the bearing, the lubrication cycle has to be extended.Buy INA Bolt Curve Roller Bearing INA KR5202 2RS E55EB
KR is similar to NUKR, except that KR has retaining rings at both ends, while NUKR only has retaining rings at one end.
6) KRV series
KRV series curved roller bearings are full complement needle roller bearings. The outer ring is axially guided through the ribs on the bolts and the ribs fixed on the bolts. It can bear heavier loads but lower speeds, but lubrication must be added frequently fat.
