Bellows Effect
INSTALLATION SEQUENCE:
1. Bushing locks to shaft
2. Tightening of bushing hub bolts pulls end disks out and up the
length of bushing
3. This stress is amplified by the distance of travel on bushing
HE Bushings and Hubs
• Specifically designed for drum and wing pulleys
• 14 degree taper angle to minimize end disc stress
• Thicker flange
• Longer length thru bore
• More mounting bolts on larger sizes
• Shaft diameters to 12”
• Even bolt spacing
• Dodge exclusive

Materials:
• SBR (Styrene-Butadiene Rubber) - standard lagging
• D-LAG - premium rubber polymer for maximum abrasion
resistance - 73% greater life than standard SBR
• Holz – replacement lagging
• Neoprene - fire retardant and oil resistant. MSHA approved
• Wing Lag - replaceable urethane slide-on lagging (CEMA only)
Arrowhead Ceramic Lagging
• Arrowhead ceramic lagging
provides the solution when
conventional rubber lagging
fails
• Increases coefficient of friction
to reduce belt slippage
• Increase wear resistance
(longer life)
* Other types of ceramic lagging available
upon request
