Loctite LB 8101 400 ml lubricant for chains, worm winches and gears, protects against water and wear, for exposed mechanisms, up to +170 ° C, contains EP additives
5
Description
LOCTITE LB 8101 400 ml is an adhesive spray lubricant for open mechanical systems—chains, open gears, worm screws and cables/wires. The mineral-oil formulation with lithium soap and EP additives builds a durable lubricating film that resists water ingress and high loads, and it is designed to withstand centrifugal forces on high-speed mechanisms.
Benefits and unique features
- Adhesive film – reduces fling-off on fast-running chains
- EP additives – excellent wear and load resistance (4-ball weld load > 3,900 N)
- Water protection – helps prevent water ingress into the mechanism
- Operating range -30 °C to +170 °C, short peaks up to ~200 °C
- Convenient spray application – fast and even coverage
Properties and applications
- Chains and sprockets: lubrication at high peripheral speeds
- Open gears, lead screws and worm drives: friction and noise reduction
- Cables and wires: improved sliding plus protection against corrosion and water
- MRO and service: industry, automotive, agriculture, conveying equipment
- How to use: shake; spray from 15–20 cm onto clean parts; avoid over-lubrication
