Introduction
The Plummer block housings are mechanical components that are used for the support of rotating shafts and bearings in various industries. For maintaining the quality, durability, and performance of such mechanical components, the Bureau of Indian Standards (BIS) has established a standard, which is called IS 14347:1996.By obtaining the BIS Certification for the product in accordance with IS 14347:1996, it is ensured that the Plummer block housings are produced in accordance with specific requirements. It is through this certification that the manufacturer can make use of the ISI Mark, which states that the product is safe to use in accordance with Indian safety and quality standards.
What is IS 14347:1996?
IS 14347:1996 is an Indian Standard developed by the Bureau of Indian Standards (BIS) for specifying requirements for plummer block housings used in mechanical and industrial sectors. This standard guarantees that the components meet specific requirements for quality, performance, and reliability.
Key Points:
- Defines Technical Specifications: It involves dimensions, tolerances, and specifications for the plummer block housing.
- Material Requirements: It involves the type of materials required for durability and strength.
- Performance Standards: It involves ensuring that the housings are able to withstand the operating conditions and environment.
- Testing Criteria: It involves criteria for testing and inspection of the quality of the products.
- Standardization Across the Industry: It involves standardization of the components.
Products Covered Under IS 14347 : 1996
The IS 14347:1996 standard, developed by the Bureau of Indian Standards, offers detailed specifications pertaining to plummer block housings, which are utilized in the support of rotating shafts along with mounted bearings. Housings are critical in the proper rotation of mechanical systems.
Key Reasons:
- Split Type Plummer Block Housings: These are used for easy installation and maintenance of bearings. The housing is divided into two parts, i.e., the cap and the base.
- Solid (Non-Split) Plummer Block Housings: These are used for applications that require infrequent disassembly. The housing is in one piece only.
- Pedestal Bearing Housings: These are mounted housings that are used for supporting shafts in heavy-duty machines and equipment.
- Housings for Different Bearing Types: These are suitable for supporting ball bearings, spherical roller bearings, and other similar rolling bearings.
- Heavy-Duty Industrial Housings: These are used for applications in industries like mining, power generation, cement, and manufacturing.
