How much does the JTEKT FH5500S-i cost?
Price estimate
We do not have a price for the JTEKT FH5500S-i 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 JTEKT FH5500S-i puts a CAT50 spindle on the 21.65 x 21.65 in (550 x 550 mm) pallet of the FH5000 Series. X travel is 35.4 in (900 mm), Y is 31.50 in (800 mm) and Z is 34.6 in (880 mm), and the spindle is listed at 15,000 RPM with 223 ft-lb (303 Nm) of torque.
That pairing is unusual and worth understanding before ordering. The taper is the large one, but the torque figure is the same 223 ft-lb (303 Nm) the table gives the CAT40 FH5000S-i. What the bigger taper buys here is a stiffer joint for long boring bars and extended tools, plus the use of holders a shop already owns for larger machines. It does not buy a heavier cut. A shop that wants the torque to match the taper should look at the FH5500SX-i, listed at 390 ft-lb (530 Nm) on the same travels.
X travel equals the maximum workpiece swing, 35.4 in (900 mm), so the full swing diameter can be reached across its width. Workpiece height goes to 43.3 in (1,100 mm). The pallet carries 2,200 lb (1,000 kg), which a tall iron fixture can use up quickly.
Tool storage is listed at 60, 120, 240 or 330. JTEKT calls the 60-tool ATC standard and the larger magazines optional. Rapid feedrate is 2,362 ipm (60 m/min) on all three linear axes, and the direct drive B-axis table indexes 90° in 0.7 seconds, so non-cutting time on four-sided work stays short. Operation is through the TOYOPUC-Touch HMI on FANUC 31iMB Plus.

Strengths & Limitations
Strengths
- CAT50 taper at 15,000 RPM on a 21.65 x 21.65 in (550 x 550 mm) pallet
- 35.4 in (900 mm) of X travel, matching the 35.4 in (900 mm) maximum workpiece swing
- Oversized roller guides and full-contact pallet clamping, per JTEKT's description of the series
- Tool storage of 60, 120, 240 or 330
- B-axis table is direct drive, with a 0.7 seconds index time for 90°
Limitations
- Torque is 223 ft-lb (303 Nm), low for a CAT50 spindle; the FH5500SX-i lists 390 ft-lb (530 Nm)
- No 20,000 RPM option in this model's table, unlike the FH5000S-i
- 2,200 lb (1,000 kg) pallet load limits heavy fixtures
- The 90 and 180 tool magazine sizes listed for the FH5000S-i are not listed here

Frequently Asked Questions
01
For the CAT50 taper and the extra X travel. The FH5500S-i has 35.4 in (900 mm) of X against 31.5 in (800 mm) on the FH5000S-i, and takes CAT50 holders instead of CAT40. Both tables give 223 ft-lb (303 Nm) of spindle torque, so the choice is about tool interface and reach, not cutting torque.
02
The spindle. Travels, pallet, workpiece limits, taper and tool storage are identical in the two tables. The FH5500S-i is listed at 223 ft-lb (303 Nm) of spindle torque and the FH5500SX-i at 390 ft-lb (530 Nm). JTEKT describes the S spindle as a 50HP peak unit with an 85mm ID dual bearing set.
03
Up to 35.4 in (900 mm) in swing diameter and 43.3 in (1,100 mm) in height, on a 21.65 x 21.65 in (550 x 550 mm) pallet rated for 2,200 lb (1,000 kg). The weight limit covers the fixture as well as the parts.
04
Rapid feedrate is 2,362 ipm (60 m/min) in X, Y and Z. JTEKT states a direct drive B-axis table with an index time of 0.7 seconds for 90°. The table does not list cutting feedrates or axis acceleration.
