About this product
Heavy-duty BLM-series sealed ball joints for control linkages, machinery, automotive and industrial applications. The housing is manufactured from high-strength zinc alloy, with a hardened GCr15 bearing-steel ball equivalent to 52100 steel and a 40Cr steel shank. An NBR rubber dust boot retains grease around the ball for wear resistance and protection from contamination. Operating temperature range is approximately -40°C to 120°C. Selected versions intentionally combine different external stud and internal housing thread sizes, providing uncommon mixed-thread configurations without requiring additional adaptors.
