Obtain BIS Certification for Ring Type Thrust Washers (Made from Strip)

Ring type thrust washers are flat, ring-shaped plain bearings that take up axial (end-thrust) loads and control the end-float of a shaft. Made from coated bearing strip and formed into a ring, they sit between a rotating face and a fixed housing, providing a low-friction sliding surface that stops metal-to-metal wear while keeping the shaft correctly positioned.

They are a common companion to engine and gearbox bearings - locating crankshafts, gear shafts, and similar assemblies - and appear across automotive, industrial, and general engineering machinery. Because they are produced and imported alongside engine bearings in large volumes, this strip-made thrust washer is covered under the Bearings (Quality Control) Order, 2025 and now requires the BIS ISI Mark under IS 9764 (Part 1):2022.

IS 9764 (Part 1):2022 standardises the dimensions and tolerances of strip-made ring type thrust washers so they fit their recesses precisely and hold the right end-float. For bearing and engine-component makers, certifying these washers alongside their main bearing range gives buyers a complete, fully ISI-marked package - a real competitive edge with OEM and aftermarket customers. Standphill India handles the IS 9764 (Part 1) licence together with your other bearing certifications as one streamlined, time-saving project.

BIS-recognized laboratories evaluate ring type thrust washer against IS 9764 (Part 1):2022 for:

• Dimensions & tolerances - inner/outer diameter, thickness per IS 9764 Part 1
• Flatness & form - flat running face within limits
• Lining material & bond - bearing coating composition and adhesion
• Hardness - backing and lining hardness
• Surface finish - sliding-face quality
• Strip formation quality - correct ring geometry from strip

Typical timeline: 8-14 weeks. Foreign manufacturers (FMCS) may take longer due to overseas audit scheduling.

• BIS application form (Manakonline)
• Factory registration proof
• MSME / Udyam certificate
• Manufacturing process flow chart
• List of machinery (grinding, heat treatment, assembly)
• List of in-house testing equipment
• Bearing steel grade details
• Product range & size designations
• Trademark / brand registration
• AIR appointment (foreign mfr.)
• BIS-recognized lab test report

Being an MSME under the Bearings QCO 2025 gives you two significant advantages: a longer compliance window (9 months for Small, 12 months for Micro) AND substantial discounts on BIS ISI Mark marking fees - the per-unit fee paid to BIS based on your annual production or import volume.
