Replacement sealing products identified by size, profile, application or existing reference.
Bridge Engineering supplies rotary oil seals, O-rings, V-rings and related shaft-repair products for industrial maintenance, repair and OEM applications.
Where the original reference is unclear, send the dimensions, operating medium, temperature, shaft speed and a clear photograph. We will help identify a suitable starting specification and confirm availability.
Metric and imperial rotary shaft seals, including common single-lip, double-lip, rubber-covered and metal-cased designs.
Standard and specialist O-rings for static and dynamic sealing, supplied by reference, inside diameter and cross-section.
All-rubber axial shaft seals that fit onto the shaft and seal against a perpendicular counterface.
The most useful starting point is the three boundary dimensions, followed by the visible lip arrangement, case construction and application conditions.
Measure the surface the sealing lip runs on.
Measure the outside diameter of the seal or housing bore.
Measure the overall axial width of the seal.
Note the marking, lip count, spring, dust lip and case style.
“35 × 52 × 7 mm, rubber-covered, spring-loaded main lip with dust lip, sealing gearbox oil.”
VA and VS are V-ring profile designations, not O-ring types. A shaft diameter alone may not distinguish the profiles, so compare the body proportions and send a side-profile photograph.
Common standard profile used across general industrial drives, motors and gearboxes.
A wider-bodied profile used where the VS design is specified; confirm body dimensions as well as shaft size.
Compact profile for restricted spaces and applications where a narrow V-ring is required.
Heavy-duty, large-diameter profile often used as additional protection for a primary seal.
Heavy-duty large-diameter design that can be clamped to the shaft for demanding arrangements.
Enter your measurements to find the closest matching O-ring sizes to AS568 / ISO 3601-1 references and metric dimensional suggestions.
The finder searches verified AS568 / ISO 3601-1 Class A dash sizes 001–050 and 102–178, plus dimensional metric suggestions. Send the application details so material and final suitability can be checked.
Measure an unstretched ring with vernier calipers where possible.
Measure straight across the inside of the relaxed ring.
Measure the thickness of the ring cross-section.
Measure straight across the outside of the ring.
Enter at least two measurements, or enter ID and cross-section.
Reference results are an identification aid only and must be checked against manufacturer data before purchase or installation.
Provide the marking where visible, shaft diameter, housing bore, seal width, lip arrangement, case style, operating fluid, temperature, shaft speed and clear photographs.
No. The finder helps identify a closest reference size. Compound, hardness, chemical compatibility, pressure and final suitability must be confirmed separately.
No. VA and VS are V-ring profile designations. Compare the side profile and measure body width and overall height as well as shaft diameter.
Yes. We can source common V-ring profiles, specialist sizes and suitable wear sleeves where a shaft sealing surface is worn.
We will help identify the likely seal type, profile and replacement options before quoting.
