HF 2016 CZH 20x26x16 Drawn Cup Roller Clutch

HF 2016 CZH is a drawn cup roller clutch with dimensions 20x26x16 mm, designed to transmit torque in one direction while allowing free rotation in the opposite direction. The HF construction combines a thin-walled drawn outer ring with needle rollers, springs and a cage, providing a compact one-way clutch solution where radial installation space is limited. The CZH HF 2016 dimensions are confirmed as 20 mm bore, 26 mm outside diameter and 16 mm width.

The 20x26x16 mm dimensions are standard for the HF2016 designation and are specifically listed for the CZH version.

HF 2016 One-Way Clutch Design

The HF series consists of compact drawn cup roller clutches. Inside the thin-walled outer ring, needle rollers interact with ramps and spring elements.

During rotation in the locking direction, the rollers engage and allow torque transmission. In the opposite direction, the mechanism overruns and permits free rotation.

This operating principle makes HF-series components suitable for overrunning, indexing and backstopping functions.

Compact 20x26x16 mm Dimensions

The key installation dimensions of HF 2016 CZH are:

Fw: 20 mm
D: 26 mm
C: 16 mm

The difference between the shaft diameter and outside diameter is only 6 mm, allowing the clutch to perform a one-way torque transmission function within a compact radial envelope.

Important Installation Information

The HF design does not incorporate an integrated radial bearing arrangement. The shaft must therefore be radially supported by a suitable separate bearing arrangement where required by the application.

This is an important distinction between the HF series and HFL drawn cup roller clutches, which incorporate an additional bearing arrangement.

Typical Functions

HF 2016 drawn cup roller clutches are used where a mechanism requires:

• torque transmission in one direction
• free rotation in the opposite direction
• overrunning function
• indexing movement
• backstopping function
• compact radial installation

The low radial section makes this design useful in compact mechanical and drive assemblies.

HF 2016 CZH Replacement Identification

For replacement selection, verify:

Designation: HF 2016
Brand: CZH
Dimensions: 20x26x16 mm
Type: Drawn cup roller clutch
Function: One-way torque transmission
Bearing arrangement: Without integrated radial bearing support

HF2016 products are available from multiple manufacturers with the same principal dimensions, but dimensional equivalence alone should not be treated as confirmation of complete interchangeability for every application.

FAQ - HF 2016 CZH

What are the dimensions of HF 2016 CZH?
The dimensions are 20x26x16 mm: 20 mm inside diameter, 26 mm outside diameter and 16 mm width.

What type of component is HF 2016?
HF 2016 is a drawn cup roller clutch, also described as a one-way or overrunning clutch.

How does HF 2016 work?
It transmits torque in one rotational direction and permits overrunning in the opposite direction.

Does HF 2016 provide radial bearing support?
The HF design does not include an integrated radial bearing arrangement. Separate radial support may therefore be required.

What is HF 2016 used for?
Typical functions include indexing, backstopping and overrunning in mechanical drive systems.

Is HF 2016 the same size from different manufacturers?
The commonly specified HF2016 principal dimensions are 20x26x16 mm, but operating parameters and execution should be checked before using another manufacturer's product as a replacement.
