**Rolling Elements: English and Chinese Terms**
Understanding the terminology related to rolling elements is essential for anyone working with bearings. These components are crucial in reducing friction and enabling smooth motion in mechanical systems. Below is a detailed list of common rolling elements along with their English and Chinese translations, as well as brief descriptions.
1. **Ball (Ball)**
A spherical rolling element used in ball bearings.
2. **Roller (Roller)**
A cylindrical or conical rolling element with a symmetrical axis and circular cross-section in either plane of the straight axis.
3. **Ball (Roller) Set**
All the balls or rollers that are part of a specific bearing.
4. **Ball (Roller) Group**
A group of balls or rollers arranged inside a bearing.
5. **Cylindrical Roller**
A roller with a straight outer surface that runs parallel to its axis.
6. **Needle Roller**
A small-diameter cylindrical roller with a high length-to-diameter ratio, typically between 3 to 10 times the diameter, but rarely exceeding 5 mm in diameter.
7. **Tapered Roller**
A roller whose outer surface is a straight line that intersects the roller axis, often forming a truncated cone shape.
8. **(Convex) Ball / Convex Roller**
A roller with a convexly curved outer surface in the plane that includes its axis.
9. **Concave Roller**
A roller with a concavely curved outer surface in the plane that includes its axis.
10. **Symmetrical Spherical Roller**
A roller with a symmetrical convex surface on both ends, passing through the middle plane and aligned with the axis.
11. **Asymmetrical Spherical Roller**
A roller with a convex surface that is symmetric about a plane perpendicular to the axis, but not necessarily symmetrical about the central plane.
12. **Convex Roller**
A roller with a slightly convex outer surface in the plane containing its axis, designed to prevent stress concentration at the ends.
13. **Rounded End Roller**
A roller with a slightly rounded end to avoid stress concentration at the contact points with the raceway.
14. **Spiral Wound Roller**
A roller made by winding steel wire into a spiral shape.
15. **Roller End Face**
The flat surface at the end of the roller, perpendicular to the axis.
16. **Large End Face of Roller**
The end face of a tapered or asymmetrical spherical roller.
17. **Small End Face of Roller**
The smaller end face of a tapered or asymmetrical spherical roller.
18. **Chamfered Roller**
A roller with a beveled edge connecting the outer surface to the end face.

Anti Fatigue Mats Industrial
The workshop is a place to stand and work for long periods of time, so the use of anti-fatigue MATS is very important for the health and productivity of employees. The following is a discussion about the necessity of using anti-fatigue MATS in the workshop and the types of options available on the market: anti-fatigue floor MATS combine various functions: fatigue relief, high elasticity, shock resistance, etc., can effectively prevent impact and fatal injuries, and are very durable for industrial and harsh environments. The shape of its bottom and surface is designed for workers to stand for a long time, which can greatly reduce the fatigue and pain caused by prolonged standing on the legs.
