I. Lubrication Shortcomings Constrain the Overall Competitiveness of Power Tool Products

Power tools are widely used in home improvement, infrastructure, and auto repair. Drills, angle grinders, rotary hammers, and other power tools long endure high-speed, impact, and high-low temperature cycling conditions; improper lubrication leads to frequent equipment failures and higher complete-unit return rates. Many manufacturers use general-purpose lubricants and suffer recurring gear wear, high-temperature cylinder carbon deposits, contact corrosion, and grease leakage — driving up after-sales costs and eroding brand reputation.

Gear, cylinder, and contact failures often stem from a mismatch between the lubricant and the operating conditions — a single grease cannot meet every need of the whole unit. FUCHS power tool greases cover lubrication points including gears, cylinders, and electrical connectors, precisely matching every application condition. FUCHS power tool lubrication solutions deliver integrated protection for the entire unit, reducing lubrication-failure losses at the source and preventing all kinds of lubrication faults.

II. FUCHS Power Tool Greases: Segmented Applications, Precise Matching

For the three vulnerable components — gears, cylinders, and electrical contacts — FUCHS has greases precisely matched to each lubrication need, with representative product models.

1. RHEOLUBE gear-dedicated grease conquers high-speed gear wear pain points

The bevel gears of angle grinders can reach line speeds of 20 m/s; high-speed centrifugal force easily flings off ordinary grease, and high temperatures accelerate grease oxidation, causing gear wear. FUCHS RHEOLUBE 380 and 380-G1 suit high-speed small gears and deliver outstanding anti-wear performance, verified by ASTM standard tests:

• Load-wear index: ordinary grease scores only 20.8, while RHEOLUBE 380 reaches 34.8 and 380-G1 reaches 35.6

• SRV load: ordinary grease reaches only 250 N, while the two products achieve 1,400 N and 800 N respectively

• Four-ball weld load: both products reach 200 kg, far above the 126 kg of ordinary grease, stably forming a protective oil film and preventing dry wear on tooth surfaces

RHEOLUBE 380 and 380-G1 offer wide-temperature, long-lasting performance, with low starting torque at low temperatures and oxidation resistance at high temperatures; RHEOLUBE 380-G1 features optimized rheological reflow, allowing the grease to flow back to the meshing surfaces during high-speed operation, balancing lubrication and leakage prevention.

In addition, RENOLIT LX-EP2 is the choice for heavy-duty circular saws, and the RENOLIT ALX series suits small and medium-load gears — FUCHS has a lubrication solution for every operating condition.

2. RENOLIT PU PTO 00 cylinder grease, suited to high-temperature reciprocating conditions in rotary hammers

Rotary hammer cylinders operate at temperatures above 100 °C and pressures of several megapascals, making grease carbonization and leakage common problems.

RENOLIT PU PTO 00 is a FUCHS power tool grease dedicated to cylinders, with excellent high-temperature rheology: a viscosity of 157 mPa·s at 100 °C, resisting thinning and leakage at high temperatures; an oxidation induction time of 57 minutes, far exceeding ordinary greases, ensures a long-lasting lubrication system; and an SRV wear scar of only 0.34 mm greatly reduces reciprocating piston wear, delivers smooth impact output, and lightens the extra load on gears.

4. Supporting auxiliary products, completing the full chain of lubrication

Beyond the core FUCHS power tool greases, FUCHS power tool lubrication solutions cover dry assembly and hydraulic scenarios: GLEITMO solid-film grease enables dry, maintenance-free assembly; RENOLIN hydraulic oils suit hydraulic wrenches and hydraulic shears, stabilizing torque output and enabling unified supply of the full range of lubrication products.

In addition, the entire FUCHS power tool grease range complies with RoHS and REACH regulations, containing no TPP/TPPT substances of high concern, or keeping them below prescribed limits — ready for export manufacturing.
