Classification and characteristics of cylindrical roller bearings

The rolling factors are radial rolling bearings of cylindrical rollers. The inner structure of cylindrical roller bearings uses rollers organized in parallel. Spacers or spacers are set up among the rollers, that could save you the tilting of the rollers or friction between the rollers, and correctly save you the boom of rotational torque.

cylindrical roller bearing category

Cylindrical curler bearings are separate bearings and are smooth to put in and take away. Cylindrical curler bearings can withstand large radial loads and are suitable to be used at excessive speeds.

Consequently, the machining accuracy of the shaft and the bearing seat is extraordinarily excessive. In any other case, choppy load or strain awareness is in all likelihood to arise at the contact part of the raceway. However, correcting the roller or raceway touch busbar can reduce the incidence of stress attention.

Cylindrical curler bearings may be divided into single-row, double-row, and multi-row cylindrical roller bearings in line with the number of rows of hooked up rolling elements. Exclusive structural bearings also are shown within the design of the position of the ribs. The typically used cylindrical curler bearings have the subsequent paperwork:

single-row cylindrical roller bearings: single-row cylindrical curler bearings are separable bearings for smooth set up and elimination. Each ferrule can be tightly fitted. The touchline between the modified curler and the raceway can reduce strain awareness.

Double-row cylindrical curler bearings: Double-row cylindrical curler bearings are movable bearings, and their separability makes set up and elimination very convenient. Each ferrule may be geared up tightly. Double-row cylindrical curler bearings are nearly in no way allowed to have a tilted attitude.

capabilities

1. curler and raceway are in line contact or repaired line touch, with a huge radial bearing capability, suitable for bearing heavy load and affect load.

2. The friction coefficient is small, suitable for excessive speed, and the limiting speed is close to deep groove ball bearings.

Three. N-type and NU kind can circulate axially, can adapt to the alternate of the relative position of the shaft and the housing due to thermal growth or installation errors, and can be used as unfastened give up the assist.

4. The processing necessities for the shaft or seat hollow are surprisingly high. The relative deflection of the outer ring axis after the bearing is hooked up has to be strictly managed to avoid touch stress attention.

5. The inner or outer ring may be separated for smooth set up and elimination

Cylindrical rollers are in linear touch with the raceways and feature a big radial load ability. It’s miles suitable for both heavy and surprises hundreds and excessive-velocity rotation.

Cylindrical curler bearing raceways and rolling our bodies are geometrically fashioned. After the improved layout, it has a higher load wearing potential. The brand new structural layout of the flange and roller stop faces now not only improves the axial bearing capacity of the bearing but also improves the lubrication conditions of the contact area between the roller cease face and the flange. We are bearing performance.
