High-Speed Bearing Grease YBS-NB52 Manufacture JLD

YBS- NB52 synthetic rolling and sliding bearing grease is a type of rolling and sliding bearing grease. Its chemical composition is based on synthetic hydrocarbon oils and complex barium soaps. Unlike other soap-based thickeners, the special barium soap-based thickener used in YBS-NB52 provides excellent load-bearing capacity, as well as resistance to water and other environmental media.

Both products exhibit good corrosion resistance, oxidation resistance, and aging stability. YBS-NB52 is suitable for temperatures from -50°C to 120°C, with a short-term peak temperature of up to 150°C, depending on its application, such as in enclosed gears and automotive seat adjustment mechanisms.

Operating Precautions

■ Ensure surfaces are clean before application.
■ Do not mix with other lubricants.
■ Avoid over-greasing.
■ Use within recommended temperature range.
■ Keep container tightly closed and avoid contamination.

How To Use

■ Clean bearing before application.
■ Apply grease evenly.
■ Fill approx. 30%–50% of bearing space.
■ Use less grease for high-speed, more for heavy-load if required.
■ Run equipment slowly after application to distribute grease.
