INA Bearings
Schaeffler's INA — the inventor of the cage-guided needle roller bearing. Trusted supply · same-day shipping · B2B quotes.
INA, founded in 1946 in Herzogenaurach, Germany, is one of two flagship brands of the Schaeffler Group and the inventor of the cage-guided needle roller bearing. Its slim cross-section and high load capacity made it the de-facto standard for engine timing systems, linear motion stages, agricultural transmissions, and any application where space is constrained but loads are not. Kovar carries the full INA range — NA, NK, NKI, RNA, NKS, NUTR, KRV, HK, HF, RWU/KWVE linear — through Schaeffler supply channels, with same-day shipping, business invoicing, and dedicated support for engineering teams qualifying replacement bearings.

INA FAQ
Where is INA based?
INA is part of the Schaeffler Group, headquartered in Herzogenaurach, Germany. The brand has led needle roller bearing and cam follower technology since 1946, and joined FAG under the Schaeffler umbrella after the 2001 acquisition.
What is INA known for?
Needle roller bearings, linear motion guides, cam followers (KRV/NUTR), and engine-timing components — applications where compact cross-section and high radial capacity matter more than the simplicity of a deep-groove ball bearing.
How does INA differ from FAG?
Both are Schaeffler brands but cover different territory: INA = needle roller, linear, cam follower. FAG = deep groove ball, angular contact, large-bore roller bearings. Schaeffler keeps the lines separate to preserve each brand's catalogue identity.
