Needle Roller Bearings
Roller bearing: It is a type of bearing that combines the characteristics of roller and needle bearings.
Model No.: CF5UU-A
Size: 5x13x9x23mm
Material: chrome steel Gcr15
weight: 0.016KG
Lead time: normally 3-5 days
Specification
CF5UU-A and CF5 cam follower needle roller bearings are both compact designs. The CF5UU-A is typically sealed, while the CF5 is open. Manufactured from chrome steel, they feature high rigidity, low friction, impact resistance, and extended service life. These bearings are suitable for applications such as cam mechanisms, linear motion systems, and conveyor systems.

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.
