Type I Timing

Type I timing features a timing system which incorporates a timing element pressed into the pulley body.

Belt Technologies has patented a process (U.S. Patent # 5,129,865) which features a hardened ball bearing as a timing element.  This provides a smooth radius for engagement and disengagement of the belt perforation.  The ball bearing is a permanently set tooth which will not come loose over time, regardless of speed or loading.

Ball Bearing sizes are relative to the belt perforation diameters and desired tooth height.

When a tooth height greater than the radius of a ball bearing is required, Belt Technologies can provide an involute tooth as the Type I timing element.  These may be custom manufactured or provided as parts from stock.
