Definition and Structure:
The roller bearing is mainly composed of the main roller, side roller, shaft head and cover plate. The main roller adopts a full-roller design and mainly bears vertical loads and impacts; the side roller adopts an open-ended full-needle structure and is responsible for horizontal loads; the shaft head is connected to the equipment, and the cover plate is used for fixing and protecting the internal components.
Performance features:
1. High load-bearing capacity: Due to the slender and densely arranged needle rollers, it can withstand a large radial load in a relatively small space.
2. Low friction: With a sealed structure and pre-filled lubricating grease design, it enables long-term maintenance-free operation and reduces wear during movement.
3. Compact design: The structure is compact, suitable for limited space applications.
4. Long lifespan: Through a reasonable lubrication design, it can increase the service life of the bearing and reduce maintenance requirements.
