Bearing classification turns on essential function; textile use does not change tariff heading, and bearing cages remain classifiable with bearings.

Foot step bearings were treated as bearings under Heading 84.63 because their essential function was to support and position rotating shafts, and their use in textile machinery did not alter that character; construction in one or more parts was immaterial. Roller retainers or metal cages were treated as parts of anti-friction bearings under Heading 84.62 because technical material showed cages are recognised components of ball or roller bearings, and the exemption under Notification No. 35/79-Cus. did not extend to that heading at the relevant time. The Department's classification was sustained and the exemption claim failed.

Issues: (i) whether foot step bearings were classifiable under Heading 84.63 of the Customs Tariff Act, 1975 as bearings or under Heading 84.38(1) as parts and accessories of textile machinery; (ii) whether roller retainers or metal cages were classifiable under Heading 84.62 of the Customs Tariff Act, 1975 and consequently ineligible for exemption under Notification No. 35/79-Cus.

Issue (i): whether foot step bearings were classifiable under Heading 84.63 of the Customs Tariff Act, 1975 as bearings or under Heading 84.38(1) as parts and accessories of textile machinery

Analysis: The tariff scheme distinguished plain shaft bearings from parts and accessories of textile machinery. The technical literature relied upon showed that plain bearings support rotating shafts, guide moving parts, and may also position shafts. Foot step bearings performed that supporting and positioning function and were therefore properly understood as bearings. Their use in textile machinery did not change their essential character, and the fact that they were made in one or more parts was immaterial because Heading 84.63 itself covered plain shaft bearings with or without housings.

Conclusion: Foot step bearings were correctly classifiable under Heading 84.63 as bearings, against the assessee.

Issue (ii): whether roller retainers or metal cages were classifiable under Heading 84.62 of the Customs Tariff Act, 1975 and consequently ineligible for exemption under Notification No. 35/79-Cus.

Analysis: The technical material showed that anti-friction bearings comprise races, rolling elements, and cages, and that cages are recognised parts of ball or roller bearings. On that basis, roller retainers or metal cages were held to fall under Heading 84.62 as parts of bearings. Since that heading was not covered by the exemption notification as applicable at the relevant time, the claim to exemption could not succeed.

Conclusion: Roller retainers or metal cages were classifiable under Heading 84.62 and were not entitled to exemption under Notification No. 35/79-Cus., against the assessee.

Final Conclusion: The classification adopted by the Department was sustained, the exemption claim failed, and the assessee's appeals were rejected while the departmental appeal succeeded.

Ratio Decidendi: Where the essential function of an item corresponds to that of a bearing, its commercial use in machinery does not alter its tariff classification, and recognised parts of bearings remain classifiable with the bearing heading unless the exemption notification clearly covers them.
