About the brand
About SKF
Inventor of the self-aligning ball bearing and the spherical roller bearing.
SKF (AB Svenska Kullagerfabriken) was founded in Gothenburg, Sweden, on 16 February 1907, on one invention: the double-row self-aligning ball bearing of Sven Wingquist, a maintenance supervisor at a Gothenburg textile factory. The factory stood on clay, so the building moved, the line shafts fell out of alignment and the rigid ball bearings of the day overheated and failed. Wingquist's bearing let the shaft run out of line without shortening its service life.
SKF invented the spherical roller bearing in 1919 and launched the spherical roller thrust bearing in 1939, the CARB toroidal roller bearing in 1995 and SKF Explorer bearings in 1999. Explorer bearings have optimized internal designs and surfaces that reduce friction and heat and carry heavier loads, for a longer service life.
In 1926 an SKF subsidiary, AB Volvo, built a trial series of cars; the first Volvo rolled out in Gothenburg in 1927.

FAQ
TKSA 41 questions & answers
TKSA 31 or TKSA 41?
Both use a red line laser with 29 mm CCD detectors, read to a 0.5% measuring error and come with SKF’s 5.6 in touch display unit. The TKSA 31’s measuring units connect by USB cable and sit up to 2 m apart, or 4 m with extension cables. The TKSA 41’s are wireless, sit up to 4 m apart, and add free measurement over a 90° turn of the shafts, a built-in camera and QR code reading for reports.
Does the TKSA 41 need a phone or tablet?
No. The TKSA 41 comes with SKF’s 5.6 in touch display unit in the kit.
Which SKF shaft alignment tool do I need?
Start from the distance and the machines. The TKSA 11 covers two horizontal machines close-coupled, with up to 185 mm between its brackets, on your own phone or tablet. The TKSA 31 (wired) and TKSA 41 (wireless) add a laser, SKF’s display unit and 2 m or 4 m between units. The TKSA 51 reaches 5 m and also aligns vertical machines. The TKSA 71 reaches 10 m and handles machine trains and spacer shafts.
What tolerance should I align to?
The machine maker’s tolerance comes first. Without one, SKF’s built-in table in the TKSA 31 and 41 allows, at the coupling: 0.10 mm offset and 0.08 mm/100 mm angle up to 2,000 rpm; 0.07 mm and 0.07 mm/100 mm to 3,000 rpm; 0.04 mm and 0.06 mm/100 mm to 4,000 rpm; 0.03 mm and 0.05 mm/100 mm to 6,000 rpm.
Does the TKSA 41 come calibrated?
Yes. The TKSA 41 ships with a calibration certificate that is valid for two years.
Which shims do I need?
SKF TMAS shims are pre-cut squares with the size and thickness marked on each one. The TMAS 50/KIT, 75/KIT and 100/KIT hold one size each (50, 75 or 100 mm) in thicknesses from 0.05 to 2.00 mm; the TMAS 340 holds 100 and 125 mm shims and the TMAS 380 50 and 75 mm. Pick the size that covers the machine’s foot.
Do you ship the TKSA 41 the same day?
In-stock orders placed by 3 PM EST ship the same day. All orders over $100 ship free by ground with code FREESHIP.
Can I get quantity pricing or buy tax-exempt?
Yes. Apollo offers special rates for businesses and bulk orders. Use Request a quote on this page or call (248) 429-9073.
Is this a genuine SKF TKSA 41?
Yes. Apollo Industries sells genuine SKF products, purchased through independent channels. Apollo is not an authorized distributor, reseller, or representative of SKF.
