Comparative Performance of HEF Bushings Versus Competitive Bushings

GARMAX vs. HEF H-LINER

• 20% less wear on H-Liner S vs GARMAX MLG after 300,000 cycles
• 20% less wear on H-Liner S1 vs GARMAX HSG after 300,000 cycles

OILES 500 Bronze with Graphite inserts vs. HEF BH2

• PEL BH2 had 29 times less wear than OILESS 500 after 430,000 cycles
• PEL BH2 has well over 15x life expectancy compared to OILESS 500
• PEL BH has a little over 7x life expectancy compared to OILESS 500

IGUS vs. HEF H-LINER

High-contact pressure scenario

• H-LINER S1 had less than 10% of the wear at 58x the number of cycles of the IGLIDUR X
• H-LINER S1 had less than 20% of the wear as the IGLIDUR Q at the same number of cycles

Low-contact pressure scenario

• H-LINER S1 had less than 40% of the wear at 44x the number of cycles of the IGLIDUR X
• H-LINER S1 had less than 40% of the wear at 4x the number of cycles of the IGLIDUR Q

Hardened Carburized Bushings vs. HEF PEL

• PEL more than 3x life expectancy
• PEL BH more than 6x life expectancy

HEF PEL BH Bushing vs. same bushing made from TOUGHMET 3CX material

• TOUGHMET 3CX Seizure after 21,000 cycles if not greased every 50 hours
• PEL BH2 lasted over 38 times longer without seizure, with only initial greasing
• PEL BH2 (greased only at installation) had less than 40% lower wear compared to the TOUGHMET 3CX bushing (greased every 50 hours)
• Even when greased every 50 hours, the TOUGHMET 3CX bushing had 6 times higher wear after 115,000 cycles, compared to the PEL BH2 using initial lubrication only
