Cylindrical Pins
Diameter: from 2.00 mm to 10.0 mm
Length: from 6.00 mm to 100.0 mm
The cylindrical pins are manufactured as per customer specifications and do not follow any standard dimensional tolerances.
- In addition to above mentioned specifications rolling elements with special tolerance limits (plus tolerances, hardness as low as 45 HRc etc) can be supplied on request.
- In addition rollers can be provided with end drops (Type ZB) as a stress relieving feature thereby increasing life performance.
- In addition rolling elements can be manufactured with different materials (Stainless Steel SS, Mild Steel MS) if the quantities required are sufficient for economical production.
Specialty material (HT)
We are capable of processing many different varieties of materials to build our customers’ parts to perform better, last longer and function for a variety of end uses.
| Material Type | Grade | Standards |
|---|---|---|
| Bearing Steel | JIS SUJ2 / SAE 52100 / DIN 100Cr6 | Standard |
| Stainless Steel | 302 / 304 / 316L | Available on request |
| High-Quality Steel | SAE 52100 | Compliant with ASTM A295 |
However, when your specs call for other steels we can explore other carbon grade and alloy steels along with various grades of stainless steel. If you’re looking for a material that’s not mentioned here, please reach out to us today for feasibility.
Needle Rollers
Needle Rollers are mainly known as Rolling Element but also act as Bearing if to be used on hard shaft and housing. Needle rollers are used where radial load and medium speeds are encountered. Needle rollers can also be useful in applications where the bearing envelope dimensions need to be kept to a minimum. Needle rollers tend to have slightly rounded ends as a stress-relieving feature, improving performance and life characteristics.

Cylindrical Rollers
Cylindrical rollers are used in bearings where the majority load is in the radial direction. Although mostly cylindrical in shape, some specialist bearings have convex barrel shapes or concave profiles depending on the application type and conditions. Pure cylindrical roller bearings cannot support any load in an axial direction. If axial support is required a separate bearing arrangement will be required.
