Timing Pulley

Timing pulley is a part that transmits the rotational power
received from the timing belt to the shaft. Our products provide
sufficient tightening force without additional processing on shafts / pulleys, etc.
and support a variety of shaft fastening methods that are easy to install.

Timing Pulley Clamping Methods

Product Features
High Accuracy
Timing Pulley has minimized backlash and it leads to high accuracy.
High Torque
The unique structure of Timing Pulley (teeth) lessens slip possibility and makes it suitable for higher torque applications.
High Speed Rotation
Designed to be used with higher RPM applications since it rarely has vibration and noise issue.
Clamping Methods
A.P.LOCK

CODE

SPA□

A.P.LOCK Type

How to work

By the taper-ring structure of A.P.Lock, when screws are fastened in a correct way, the inner surface shrinks inwards so it tightens the shaft. At the same time, the outer surface becomes expanding outwards so it clamps Timing Pulley tightly.

Feature

With high clamping force itself, it doesn’t require any other complementary methods e.g. keyway.

SPB

TAPER BUSHING Type

How to work

By the taper-ring structure of Taper bushing, when screws are fastened in a correct way, the inner surface shrinks inwards so it tightens the shaft.

Feature

With high clamping force itself, it doesn’t require any other complementary methods e.g. keyway.

Easy and handy installation
SIDE-CLAMP

SC

SIDE-CLAMP Type

How to work

Clamp with fastening screws in a vertical way to the shaft and make the hub’s inner surface shrink inwards so it tightens the shaft.

IDLER Type

Feature

The inner diameter of the timing pulley has an inserted ball bearing, which is used for adjusting the tension of the timing belt, changing direction, or functioning as the driven pulley.
