VIIPLUS — Free Every Machine from the Constraints of Lubrication

Self-Lubricating Bearing Total Solutions · From Material to Finished Product, One-Stop Delivery

I. Brand Positioning

VIIPLUS is a Chinese company specializing in the R&D and manufacturing of high-performance self-lubricating bearings, headquartered in Jiaxing, Zhejiang. We serve global industrial customers as a tribology design partner. We are committed to helping small and medium-sized enterprises reduce costs, extend equipment service life, and improve operational reliability—turning “maintenance-free” from a design concept into a practical engineering reality.

Self-lubricating bearings embed solid lubricants into the material structure, eliminating the need for oil lines, grease fittings, or relubrication schedules. This fundamentally removes an entire class of failure sources: missed lubrication, lubricant contamination, and lubricant breakdown at extreme temperatures. For design engineers, this means risk shifts from field maintenance to the design-stage specification sheet. For equipment operators, it means one less item to schedule—and one less thing to forget.

II. Product Matrix

VIIPLUS offers a complete product line covering working conditions from dry running to oil lubrication, including steel-backed PTFE composite bearings, POM boundary-lubricated bearings, bimetal bearings, wrapped bronze bearings, and graphite-embedded bronze bearings.

VSB-10 Technical Highlights: A three-layer structure consisting of low-carbon steel backing + sintered porous bronze layer (0.20–0.35 mm) + PTFE/fiber mixture running layer (0.01–0.03 mm). During operation, a thin transfer film forms on the mating shaft surface. It supports dry running and also works stably under oil-lubricated conditions. Suitable for rotary, oscillating, and reciprocating motion. Certified to FDA, USDA, and EU food-contact safety standards. Service life can be 2–5 times that of conventional solutions.

III. Core Technical Advantages

Truly Maintenance-Free

Solid lubricant is embedded within the bearing structure, with no external oil supply system required. This is not just about eliminating a grease fitting—it removes three typical failure modes: missed lubrication, lubricant contamination, and lubricant inability to withstand high temperatures. It also saves the labor and downtime costs associated with maintenance intervals, while keeping surrounding equipment clean.

Reliability Under Extreme Conditions

Graphite-embedded bronze bearings are specifically designed for harsh environments where conventional grease lubrication fails: high temperatures, heavy loads, hard-to-reach lubrication points, or low-speed heavy-load oscillating motion. In a steel plant stacker-reclaimer bucket wheel mechanism, after VIIPLUS solid-lubricated bearings replaced conventional roller bearings, the maintenance interval was extended from every 3 months to more than 3 years.

Materials Science Driven

VIIPLUS offers a variety of copper alloy options—aluminum bronze CDA 954 (seawater and chemical corrosion resistance, suitable for marine rudder bearings), bearing bronze CDA 932/SAE 660 (good embeddability and anti-seizure properties, suitable for conveyor roller table bushings), and manganese bronze CDA 863 (highest tensile strength, suitable for cone crusher eccentric sleeves)—ensuring the optimal material match for every type of working condition.

Full-Cycle Quality Control

VIIPLUS has established a full-process quality control system from raw materials to finished products, strictly implementing inspection standards at each manufacturing stage. The company products comply with international standards such as ISO 3547 and DIN 1494.
