QA1 MHMR20Z HM Series Male Rod End with Zerk Fitting

The QA1 MHMR20Z is a precision three-piece male rod end from the HM Series, featuring chromoly steel construction with a grease zerk fitting for extended service life. This high-performance rod end utilizes QA1's proven three-piece design where the ball is pressed into a sleeve, swaged, and then staked into the body, delivering superior ball-to-race conformity and tighter tolerances for demanding applications.

Construction and Materials:

• Ball: 52100 bearing steel, heat treated, hard chrome plated, and precision ground for maximum durability
• Race: Chromoly heat-treated steel with corrosion and wear-resistant finish
• Body: Heat-treated chromoly steel with protective coating for corrosion resistance
• Grease Fitting: Zerk fitting allows for periodic lubrication to maintain performance

Key Features:

• Three-piece precision design for tighter tolerances and improved reliability
• Heat-treated chromoly construction throughout for exceptional strength
• Hard chrome plated ball for reduced friction and extended wear life
• Corrosion-resistant protective coating on all components
• Male thread configuration for linkage and suspension applications
• Serviceable design with grease zerk for maintenance

The HM Series rod ends are ideal for race cars, off-road vehicles, and high-performance street applications where precision, durability, and tight tolerances are critical. The chromoly construction provides superior strength compared to standard carbon steel rod ends, while the grease fitting ensures long-term performance in harsh environments.
