Q: How much does the Thielenhaus BearingStar 200 cost?

The price estimate for the Thielenhaus BearingStar 200 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/thielenhaus-bearingstar-200#price; the request is passed to Thielenhaus Technologies or an authorised dealer.

Uncertain

We do not have a price for the Thielenhaus BearingStar 200 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Thielenhaus BearingStar 200 is the mid-size machine of the BearingStar range, for outer rings of 85 – 200 mm (3.3 – 7.9 in) outside diameter and inner rings of 50 – 180 mm (2.0 – 7.1 in) inner diameter. Ring width runs from 15 – 80 mm (0.59 – 3.1 in). Thielenhaus builds it with 1 or 2 machining stations as a fully automatic Microfinish machine for ball and roller bearing inner and outer rings.

Stone force is where this size departs from the smaller machines. Stone contact pressure is 80 – 360 N, more than double the 170 N ceiling of the BearingStar 90, and it cannot be set below 80 N. The workpiece spindle is correspondingly slower at 0 – 3,000 rpm. Oscillation is unchanged: 0 – 1,200 double strokes per minute, with ±0 – 18° of angle or 0 – 6 mm (0 – 0.24 in) of linear stroke.

With two stations the machine runs the 2-step method, pre-finishing on one stone and finishing on the next. Thielenhaus's product page lists 1-stage processing at one station, 1- or 2-stage processing on 2 stations, outer and inner ring machining, and oscillation units with direct drive or mechanical. It calls the 200 series a universal machine platform for all bearing types, though it does not list the ring types one by one for this size.

The ranges overlap with the neighbours. Rings of 180 – 200 mm outside diameter also fit the BearingStar 320, which has the same spindle speed and stone pressure but is listed with 1 machining station. If a programme needs two stations at that diameter, this is the machine that offers them.

Frequently Asked Questions

01 What ring sizes does the BearingStar 200 cover?

Outer ring outside diameter 85 – 200 mm (3.3 – 7.9 in), inner ring inner diameter 50 – 180 mm (2.0 – 7.1 in) and ring width 15 – 80 mm (0.59 – 3.1 in). Below that the BearingStar 120 covers 60 – 120 mm outside diameter, and above it the BearingStar 320 covers 180 – 320 mm.

02 How many machining stations can it have?

1 or 2. Thielenhaus lists 1-stage processing at one station and 1- or 2-stage processing on 2 stations. The BearingStar 320 and BearingStar 650 are both listed with 1 machining station, so this is the largest BearingStar size shown with a 2-station choice.

03 How much stone contact pressure is available?

80 – 360 N. That is the same range as the BearingStar 320 and well above the 0 – 170 N of the BearingStar 90. The lower limit of 80 N means very light finishing passes are work for the smaller machines.

04 What are the spindle and oscillation figures?

Workpiece spindle speed is 0 – 3,000 rpm. Oscillation frequency is 0 – 1,200 double strokes/min, with an oscillation angle of ±0 – 18° or a linear oscillation stroke of 0 – 6 mm (0 – 0.24 in). The product page lists oscillation units with direct drive or mechanical.
