chain grease nipples

Industrial chain grease nipples are manufactured from alloy steel with chrome or nickel coating to enhance wear and corrosion resistance. Shaft lengths typically range from 20 to 150 millimeters, with inner diameters between 10 and 50 millimeters, designed for temperatures from -20°C to 120°C. Grease capacity reaches up to 50 cc per unit, with working pressure up to 5 bar. NBR or FKM rubber seals prevent dust and water ingress, extending service life beyond 30,000 hours.

Installation on chains uses standard M6 to M12 bolts, with grease entry angles adjustable from 30 to 60 degrees depending on chain type. The lubrication system includes SAE connectors and high-pressure hoses, verified by hydrostatic and dynamic testing for continuous performance. Component design complies with ISO 12100 and DIN 51502 standards, ensuring safety and operational efficiency.
