Belting for Slider-Bed Conveyors

A low-friction bottom surface allows belting to slide along slider-bed conveyors.

Neoprene resists oils and won't shrink. It has a low-friction top.

White Buna-N is for food applications when used with stainless steel lacing. It resists animal fats and oils.

Orange Buna-N is also known as MOR belting due to its mild oil resistance.

Vinyl/Buna-N has a glossy cover that is nonstaining, impervious to hot water, and resists fats, oil, and grease.

Polyurethane has a glossy top cover that resists stains and sticking. It is more durable than Buna-N with a glossy top.

Rough-Top Belting for Slider-Bed Conveyors

The textured surface grips packages and cartons to prevent material from slipping when traveling on inclines and declines. A low-friction bottom surface allows belting to glide along the bed of the conveyor. Use belting with hammer-on hook-style lacing or quick-install hook-style lacing.

Note: The top surface of the belt ends should be removed with a conveyor belt shaver or skiver before installing lacing. Recommended lacing is based on the thickness of the belt after removing the top surface.

Neoprene has a good grip along with superior oil resistance.

Buna-N has a hard textured surface that resists punctures and abrasion.

SBR has good impact resistance and an excellent grip.
