MJ35B-370 MJ35B-550 High Speed Motor for End Cutting Woodworking Machinery Parts

Need a spare trimming motor that drops straight into an edge banding line? The MJ35B-370 and MJ35B-550 are high frequency spindle motors for the end cutting unit of automatic edge banding machines. 0.37 kW (0.5 HP) and 0.55 kW (0.75 HP), both at 12,000 r/min, S1 continuous duty, class F insulation, IP54, in left and right hand. Other name: high frequency trimming motor.

A shop running an automatic edge banding line runs into the same three things: a trimming unit that tears the glue line on the panel edge, a spare motor that takes weeks to arrive from overseas, and a replacement that turns out not to fit the head already on the machine. The MJ35B series exists for those three.

The MJ35B-370 and MJ35B-550 are high frequency spindle motors, also sold as high frequency trimming motors, that mount on the end cutting unit of an automatic edge banding machine in the woodworking industry. Two power steps cover most lines: 0.37 kW (0.5 HP) as MJ35B-370 and 0.55 kW (0.75 HP) as MJ35B-550. Both turn at 12,000 r/min.

At 12,000 r/min the cutter shears the overhanging edge before the glue sets hard, and the fast cut leaves the fracture surface smooth instead of furred. Left hand and right hand motors are both supplied, so a two-head trimming station can be fitted as a matched pair from the same order.

Both models are rated S1 for continuous running, with class F insulation on the winding and IP54 enclosure protection. The short, small-sized body keeps the trimming head mechanism simple, and the MJ series is designed to replace similar imported motors rather than force a new head. Each motor is packed in a standard export carton box.

What decides whether a spare motor drops into your line:

• Two power steps, one duty rating — 0.37 kW (0.5 HP) as MJ35B-370 and 0.55 kW (0.75 HP) as MJ35B-550, both 12,000 r/min, so one spare family covers both heads.
• Fast shear, clean edge — 12,000 r/min at the cutter removes the overhanging edge in one pass, and the fracture surface stays smooth enough to ship.
• Left and right hand — Both directions are supplied, so the two heads of a double-end trimming station come from one order.
• S1 continuous duty — Rated S1, meaning the motor is built to run through a full shift of panels back to back, not in short bursts.
• Class F insulation — The winding is class F, the temperature class this motor is built to, which suits a head sitting near the glue pot.
• IP54 enclosure — IP54 keeps chipboard dust and splashes off the winding inside the machine cabinet.
• Smooth at full speed — Low noise, no vibration and smooth rotation at 12,000 r/min keep the cut steady across a long run of panels.
• Torque held at speed — High frequency drive keeps torque up at full speed, so the cutter does not bog down on a thick edge.
• Compact body — A short housing and simplified mechanism keep the end cutting unit compact, which counts when two heads share a station.

The choice today is usually between the imported motor on imported lead time and a cheaper unit that fails inside a season. Neither is a plan. Here is what changes:

• Your line keeps running. A 0.37 kW or 0.55 kW motor on the shelf turns a failed trimming head into an hour of maintenance instead of a production stop.
• Edge quality you can invoice. 12,000 r/min shear leaves a fracture surface that still looks clean under raking light, so panels ship without hand-scraped corners.
• One family, both heads. The MJ35B-370 and MJ35B-550 come in left and right hand, so a double-end station is covered by one spare parts list and one supplier.
• Maintenance set by the cutter. S1 duty and a class F winding mean the service interval follows cutter wear rather than motor duty, which is easier to plan.
• Protection that suits the shop. MDF and chipboard dust is what kills a trimming motor; IP54 keeps it out of the winding, so the motor survives the cabinet it lives in.
• Shipping matched to the order. Air, sea or express is chosen by order quantity and freight is quoted once the destination is known, so one motor or a pallet of motors both move.

Match the motor to the load on the trimming head, not to the machine brand. 0.37 kW (0.5 HP) MJ35B-370 suits a light end cutting head; 0.55 kW (0.75 HP) MJ35B-550 is for a head carrying more load. Both turn 12,000 r/min, so edge finish is set by the cutter, not by the power step.

Yes, that is what the MJ series is designed for. It is built as a replacement for similar imported motors on automatic edge banding machines. Send the nameplate details of the motor you run — power, speed and hand — and we confirm the match before you order.

Yes, both directions are supplied. A double-end trimming station needs one of each, and both can come from the same order, so you are not hunting a second part number.

12,000 r/min on both models. That is the speed the end cutting head is designed around, so the shear action on the overhanging edge stays the same whether you fit the 0.37 kW or the 0.55 kW unit.

Yes. Both models are rated S1 continuous duty, so the motor is built to run panel after panel through a full shift rather than in short start-stop bursts.

IP54 enclosure, with a class F winding inside. Chipboard and MDF dust off the trimming head is kept out of the winding, and splashes are kept off as well.

Price is quoted per order rather than listed. Tell us the model, the hand and the quantity, and the quote comes back for that exact combination — a single spare and a line stock are not the same price.

It ships in a standard export carton box. Shipping is by air, by sea or by express, chosen by order quantity, and the freight figure is updated once we know the destination.
