INA bearings, sold & sourced by Dalton Bearing Service
Dalton Bearing Service supplies INA needle roller bearings, cam followers and track rollers, cylindrical and crossed roller bearings, thrust bearings, radial insert ball bearings, plain bearings and linear guidance from our counter at 601 S Glenwood Ave in Dalton, Georgia. INA is the Schaeffler Group's original brand. Schaeffler now markets most of these products under its own name, but the INA marking is still on the parts and the INA part numbers still apply, so this page is a plain guide to what INA makes and how to order it.
Needle roller bearings are INA's core line: drawn cup needle roller bearings (HK, BK), machined needle roller bearings with and without inner rings (NK, NKI, NA), needle roller and cage assemblies (K), and needle and axial roller thrust bearings (AXK, AXW).
Cam followers and track rollers come in stud type (KR, KRE, NUKR, with eccentric collars for adjustment) and yoke type (NATR, NATV, NUTR), in single and double row versions. Conveyors, packaging lines and textile machinery here in northwest Georgia use a lot of them.
Crossed roller bearings have rollers arranged in an X pattern, so one bearing carries radial, axial and tilting loads, which suits rotary tables and robot joints. INA also makes full-complement and caged cylindrical roller bearings, angular contact and radial ball bearings, and radial insert ball bearings (GRAE, GE..KRR-B) with matching housed units.
INA plain bearings include spherical plain bearings and rod ends. INA linear guidance covers profiled rail guides with ball (KUVE) and roller (RUE) recirculation, linear bushings and track roller guides. On the automotive side INA supplies idler pulleys, belt tensioners and sprockets, plus engine, transmission and powertrain components.
Send us the full INA number, suffixes included, or a photo and the shaft size. If it is on backorder we will tell you up front and offer an equivalent, often from the same Schaeffler catalog.
INA ownership & history
INA was founded in 1946 in Herzogenaurach, Germany, by the brothers Dr. Wilhelm and Dr. Georg Schaeffler. The name comes from Industrie-Nadellager (industrial needle bearings). Around 1949-1950 Georg Schaeffler developed the cage-guided needle roller bearing. The cage kept the needles parallel, which made needle bearings reliable enough for mass industrial use and built INA's business worldwide. INA set up its US operation in the 1960s around Cheraw, South Carolina, and its North American headquarters is now in Fort Mill, South Carolina.
INA bought the clutch maker that became LuK in 1965 and took LuK over fully in 1999. In 2001 INA won control of FAG Kugelfischer, the much older ball bearing maker in Schweinfurt. In 2003 the three companies were grouped as the Schaeffler Group, with INA, FAG and LuK kept as product brands. Schaeffler has since put its own name first in its marketing and packaging, but INA part numbers and the INA marking on the parts remain in use.

Why buy INA bearings from Dalton Bearing
Dalton Bearing Service has kept plants running from Dalton, Georgia since 1946.
