🔍 What to Know About Rubber Oil Seals (50 mm–150 mm)

Most common: NBR (Nitrile Rubber) — good resistance to oil. ashutoshrubber.com+1
Other materials: EPDM, FKM, depending on temperature and chemical compatibility. fpparis.in+1
For very large seals, sometimes a metal insert is used for structure. fpparis.in

Oil seals are generally specified as: ID × OD × Width (for example, 90 × 150 × 13 mm). Moglix
Tolerances on outside diameter matter. For rubber oil seals, tolerances increase with size (see standards for 50–80 mm, 120–180 mm etc.). ashutoshrubber.com

Single-lip vs double-lip: Double-lip offers better sealing (for oil + contaminants). For example, a 150×180×15 mm double-lip seal is available. Implemental
Spring-loaded lip gives constant contact pressure for better sealing. Implemental

Choose the right rubber grade depending on operating temperature and the rotational speed of the shaft.

Large manufacturers (like Ashutosh Rubber) follow DIN standards and provide detailed dimension tables. ashutoshrubber.com
Distributors like Moglix sell many sizes; for example, B K Jagan & Co offers a 90×150×13 mm seal. Moglix
For custom or bulk sizes, look at sealing companies that support sizes up to and beyond 150 mm. fpparis.in

First, measure precisely the inner diameter (shaft), outer diameter (housing), and width needed — very important for a proper seal.
Decide on lip type — single-lip may be enough; double-lip + spring is more reliable for high-dirt or high-pressure environments.
Choose rubber compound based on your operating conditions (temperature, oil type).
Buy from a trustworthy industrial seal supplier (Moglix, Implemental, Ashutosh Rubber) to ensure quality.
