BIS Certification for Plain Bearings Ring Type Thrust Washers Made from Strip IS 9764 (Part 1)

The Bureau of Indian Standards (BIS) has made BIS Certification for Plain Bearings Ring Type Thrust Washers compulsory under the Bearings (Quality Control) Order, 2025. Ring-type thrust washers, made mainly from strip material, provide a cost-effective solution for axial load applications with limited space. IS 9764 (Part 1) has been outlined to ensure the quality, safety, and durability. It specifies the dimensions and tolerance for these components. 

Let's read more to get complete details about the ISI Certification of Plain Bearings, Ring Type Thrust Washers Made from Strip.

 

Overview of Plain Bearings, Ring Type Thrust Washers Made from Strip

The BIS Certification of Plane Bearings Ring Type Thrust is crucial as it provides safety, durability, and trust to the consumer. They are made to support axial loads in machines. They are made from strip material and typically used in situations that require low friction and high wear resistance. They are a part of the functionality and longevity of different mechanical systems.

 

Thrust forces created by high-speed rotating machinery are normally a critical factor in most designs. Used in automotive transmissions, pumps, compressors, and industrial equipment, ring-type thrust washers are typically made from strip material to keep costs down and for applications with axial load constraints on space. Ring-type thrust washers are compact flat bearing components for axial loads that serve to reduce friction between moving parts. 

 

BIS Scope for Plain Bearings, Ring Type Thrust Washers 

This standard (Part 1) specifies a range of thrust washers for general-purpose use with Plain Bearings And Wrapped Bushes, applicable to thrust washers that have inside diameters ranging from 6 mm to 80 mm.

 

BIS Quality Control Order (QCO) for IS 9764

The Bureau of Indian Standards (BIS) Quality Control Order (QCO), Plain Bearings, Ring Type Thrust Washers Made from Strip, applies to the quality control of these bearings under Indian Standard IS 9764 (Part 1) 2022 and to ensure safety, quality, and reliability.

Several factors to consider for QCO are as follows:

• Standard: The QCO specifies that Plain Bearings, Ring Type Thrust Washers Made from Strip must meet the requirements of the stated standards IS 9764 (Part 1)
• BIS Certification: Manufacturers and importers of Plain bearing Ring Type Thrust Washes made from strip are required to have ISI Certification and footprint testing to ensure conformity with the relevant Indian Standard. 
• Compliance Check: BIS will continue to perform compliance checks, which ensure compliance with QCO through market surveillance, which is obtained by sampling the market. There might be some exceptions in QCO for some circumstances, for example, exports and R&D.

 

Key Specification of IS 9764 (Part 1)

Summary of Plain Bearings Ring Type Thrust Washers—-------- Dimensions and tolerance:

• Scope: Applies to ring-type thrust washers made from a strip of material. Provided for thrust washers with internal diameters from 6 mm to 80 mm.

 

• Dimensions & Tolerances: The standard states: Inside diameter (d), Outside diameter (D), Thickness of wash (eT), Pitch circle diameter (C), Dowel hole diameter (F), Limit of Flatness (p). Dimensions and tolerances are based on a G10 classification to provide dimensional interchangeability and repeatable performance.

 

• Grooving and Surface Finish: Oil grooves may be incorporated by mutual agreement for enhanced lubrication. All sharp edges shall be removed for safety and operational efficiency. Flatness has not been specified for grooved thrust washers, due to expected distortion when thruster washers are embossed.

 

• Chamfers: All sharp edges shall be removed.

 

• Material: All materials for the lining of the thrust washers and the backing steel shall be as described in Annex A and Annex B.

 

• Workmanship & Finishing: All sharp edges shall be removed. Cracks in the lining material in the locations of the grooves may be tolerated; however, no loose material shall be tolerated.

 

• Marking: Ring-type thrust washers shall be marked with the external dia, wall thickness, original/ repair size, manufacturer's mark, and standard number.

 

BIS Certification Procedure for IS 9764 (Part 1): Plain Bearings Ring Type Thrust Washers Made from Strip

BIS Certification process for Plain Bearings - Ring Type Thrust Washers From Strip conforms to IS 9764 (Part 1) involves the following steps:

• Application and Compliance: Manufacturers will have to adopt BIS standards and find the relevant one (in this case, IS 9764 (Part 1)), then fill out the BIS Certificate registration through the BIS system for consideration. After identifying the standard, a formal application is made to BIS.

 

• Factory Inspection: Following the application, BIS will have inspectors examine the manufacturing facility thoroughly. The inspectors will assess the quality control system, testing capability, and whether the factory meets the relevant standard; however, they cannot assess against an unfinished standard (if the market for the product exists or is developing).

 

• Product Testing: Once a factory inspection is satisfactory, the inspectors will commence sampling and draw items from the production lot to send to BIS-recognized laboratories to carry out testing. These tests are to ensure compliance with IS 9764 (Part 1); if samples fail to meet specifications, BIS will quarantine the lot in question and ascertain the extent of non-compliance.

 

• Certification and Licence: If the factory meets all BIS specified requirements and qualifies testing samples above the minimum score, a licence is issued granting the right to the Standard Mark. The Standard Mark (ISI) must be displayed on the certified product.

 

• Surveillance: BIS will conduct periodic inspections to confirm ongoing compliance with requirements. BIS may withdraw samples from BIS product certification for further testing. 

 

BIS certification can be obtained for both: 

• BIS Mark Certification Procedure for Indian Manufacturers
• BIS Mark Certification Procedure for Foreign Manufacturers

 

What are the timelines for Plain Bearings, Ring Type Thrust Washers, and BIS Certification?

India has a range of BIS certification timelines for various types of producers. They are BIS Certifications to Indian Manufacturers, normally issued within 30 days, and for FMCS BIS Certification for Foreign Manufacturers, issued within 180 days.

 

Importance of BIS Certification for Plain Bearings, Ring Type Thrust Washers
