Bronze Plain Bearings
TOP BEARINGS provides cost-effective precision bronze bearings & wear plate solutions and assemblies for the medical industry, agricultural, mechanical handling and lifting applications.Bearing forms made to order: standard forms in special dimensions, thrust washers, flanged thrust washers, half-bearings, special shapes obtained by stamping or deep drawing, customized bearing designs.we provide services for the automotive industry in the production and assembly of dies sliding bearing. we manufacture washer sliding plate and graphite bronze bushing for making mould components.customized items standard components for injection mold metric plate bronze gleitlager gasket.
We TOP bronze bearings offers various types of bronze wear plates, ranging from unfinished cast bronze plate to fully finished machined components. below are descriptions of the various types we offer.wear plates guide and control linear motion when there are heavy forces to contend with. these plates act as linear bearings to guide and control movement.
Standard Mold Components
Sliding Block olid Bronze Metallic Self-lubricating Bearings
Solid Lubricant Cast Bronze Bearings Silde Block With Immediate Running Velocity
Metric Bronze Bushings Block Tin-Bronze For Metallurgy / Drying Machine
Cast Bronze Bearing with Graphite Plugs
Copper Cast Bronze Bearings Slide Block Anti Abrasion For Transportation Machines
1. May work without any ol for long period
2. Extremely high load capacity, good anti-wear and lower friction
3. Particularly appropriate for low speed and high load
4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃
Aluminum-Bronze With Solid Lubricant Casting Bronze Silde Block
Aluminum-Bronze Solid Lubricating Silde Block is backed with Aluminum-Bronze alloy with good capability of mechanics, castings and anti-erosion. The surface of Aluminum-Bronze Solid Lubricating Silde Block is regularly and finely machined with sockets in which particular solid lubricant is filled.
Aluminum-Bronze Solid Lubricating Silde Block is widely used conditions with mediate load but higher temperature and condition with mediate running velocity etc.
The surface of Aluminum-Bronze Solid Lubricating Silde Block is regularly and finely machined with sockets in which particular solid lubricant is filled.
Strusture
TOB-50P Sliding Block material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
