Focus on the Bearing Industry for 20 Years!
Introduction to sub-categories:
Cylindrical rollers and raceways are in line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the retaining edge of the ring is small, which is suitable for high-speed rotation.
EW series products with large load capacity are available.
With polyamide forming cage (ET type), it can be used continuously in the temperature range of -40～120℃. However, if it is to be used at a high temperature of 100°C or higher in the environment of gear oil, flame-retardant operating oil, and synthetic ester oil.
The full complement roller type cylindrical roller bearing has no cage and can be assembled with the maximum number of rollers. Therefore, the load capacity is very large.
However, because it is a full-load roller type, it is inferior in terms of high-speed performance compared to a bearing with a cage. Open single-row and double-row bearings are mainly used in the low-speed and high-load fields of general industrial machinery, and dust-proof double-row bearings are mainly used for crane steel rope pulleys.
Because of the contact seal ring, the effect of preventing the intrusion of foreign matter and water is excellent.
2. Large load capacity:
As a bearing for pulleys, it has a large radial load capacity and thrust load capacity.
3. Corrosion resistance:
Through phosphate coating treatment, the anti-rust ability is improved.
4. Grease replenishment type:
It is a sealed bearing. At the same time, grease can be supplied through the inner ring with a grease hole.
5. Reduced installation parts:
With the outer ring retaining ring, the sealing performance is good, so the number of parts around the bearing can be reduced, and the cost of the overall structure of the pulley can be reduced.
