Oil Seal Manufacturer
SBT is an experienced oil seal manufacturer supplying standard and custom sealing products for industrial equipment, automotive systems, agricultural machinery, pumps, motors, gearboxes and other mechanical applications. Our product range covers general-purpose rubber oil seals, high-temperature seals, metal-cased designs, double-lip seals, crankshaft seals and application-specific sealing components.
Whether you are sourcing an available size, replacing an existing part or developing a seal from a drawing or sample, SBT can help you compare the structure, material and supply option before quotation. As an oil seal supplier serving OEMs, distributors and maintenance markets, we support both recurring production orders and wholesale oil seals for international procurement.
Oil Seal Products Available from SBT
Standard Rubber Oil Seals
Standard rubber oil seals are suitable for retaining lubricants and excluding dust or other contaminants in general rotary equipment. Available structures and materials depend on the required size and operating conditions.
Industrial CFW1 Oil Seals
CFW1, VA and VS designs are available for industrial rotary applications such as gearboxes, motors, pumps and conveying equipment. Buyers can submit the required dimensions and application conditions for product confirmation.
High-Temperature Oil Seals
For equipment operating above the normal temperature range of general-purpose NBR, material compatibility must be confirmed according to the actual temperature, medium and operating time. SBT supplies FKM and other material options for demanding industrial applications.
Double-Lip Spring-Loaded Oil Seals
A double-lip design combines a primary sealing lip with an auxiliary lip for additional contaminant exclusion. Spring-loaded structures help maintain contact between the sealing lip and shaft under appropriate operating conditions.
Agricultural and Heavy-Duty Oil Seals
COMBI and cassette-type products are designed for equipment exposed to mud, dust, moisture and other external contamination. For a wider selection by agricultural equipment type, visit our dedicated agricultural sealing range.
Crankshaft and Large-Size Oil Seals
Crankshaft seals require accurate matching of the shaft, housing, lip structure and operating environment. Please confirm the dimensions and equipment information before placing a replacement or production order.
Oil Seal Types and Supply Options
SBT supplies oil seals in common structures such as TC, SC, TB, TA, SB, SA and VC, subject to size and application requirements.
Single-lip oil seals for lubricant retention in relatively clean operating conditions
Double-lip oil seals for lubricant retention and additional dust exclusion
Rubber-covered outer diameter seals for housing conformity
Metal-cased oil seals for applications requiring a rigid outer structure
Cassette and COMBI seals for contaminated and heavy-duty environments
End cover seals for closing unused housing bores
Standard metric and non-standard sizes
OEM oil seals manufactured according to drawings, samples or confirmed specifications
Standard Sizes or Custom Oil Seals?
Standard oil seals are generally the first option when the required dimensions, material and lip design are already available. They can reduce development work and are suitable for replacement, distribution and routine equipment production.
Custom oil seals may be required when:
The shaft or housing uses a non-standard dimension
A standard compound is incompatible with the operating medium
The equipment operates under unusual temperature, speed or contamination conditions
The buyer requires a specific lip, metal case, spring or outer-diameter design
An obsolete seal must be reproduced from a drawing or sample
OEM branding or customized packaging is required
SBT evaluates standard and custom supply separately so that buyers can compare tooling, sampling, order quantity and production schedule before confirming an order.

Our oil seals are used in:
Gearboxes and reducers
Electric motors and generators
Industrial pumps and compressors
Automotive engines and transmissions
Agricultural and construction machinery
Tractors, harvesters and other farm equipment

This page provides an overview of the complete product range. For application-specific selection, use the corresponding agricultural, tractor or rotary shaft seal category rather than relying only on a general product description.
