HFL 3530 INA 35x42x30 - needle roller bearing

Applications

The HFL 3530 INA 35x42x30 is a compact needle roller bearing with an integrated one-way clutch, designed for high radial loads where installation space is limited. It is widely used in industrial applications such as gear drives, transmissions, automation systems, packaging machines and conveyor equipment. The bearing can operate as part of a bearing housing or within a complete bearing unit, simplifying drive system design.

Advantages

The needle roller design provides a very high radial load capacity relative to its size. The integrated one-way clutch allows free rotation in one direction and locking in the opposite direction, eliminating the need for additional components. Precision manufacturing by INA ensures high durability, low friction and reliable operation under continuous duty. Compared to a ball bearing, the HFL 3530 offers higher load capacity and added functional value in compact assemblies.

Main description

The HFL 3530 INA 35x42x30 is a specialised needle roller bearing with an integrated one-way clutch, developed for modern drive systems requiring compact design and reliable performance. The needle roller arrangement enables the bearing to carry high radial loads while maintaining a small outer diameter, making it ideal for space-saving constructions.

The built-in one-way clutch transmits torque in one direction and overruns freely in the other, simplifying mechanical layouts and reducing the number of components. Precision manufacturing by INA ensures stable operation, low friction and long service life in demanding industrial environments. In many cases, this bearing provides a functional advantage over a standard ball bearing, combining load capacity and directional control in a single unit.

With standard 35x42x30 dimensions, the HFL 3530 can be easily integrated into existing designs or used as part of a complete bearing unit. It is a proven solution for B2B customers seeking durability, compactness and reliable performance in continuous-operation machinery.
