HOLZMANN SF444N-8 Power Feeder — 4 Rollers, 8 Speeds
SF444N-8
The HOLZMANN SF444N-8 is a four-roller power feeder with eight feed speeds from 3.5 to 34 m/min and a 1050 W S6 (750 W S1) motor on 400 V. Four feed rollers of 120 mm diameter and 60 mm width keep long stock under drive through the whole pass, on a 60 kg net head adjusted by dual rod device.
The SF444N-8 price moves with the mounting column or bracket specified for your machine, the 400 V connection work on site, freight and customs on a 66 kg gross and 770 mm long shipment from Austria, and whether commissioning and training are added.
ფასის მოთხოვნაFour rollers for long stock on an eight-speed drive
Board length, not motor size, is what usually decides between the two eight-speed feeders — and that is where the SF444N-8 answers. Four feed rollers hold the workpiece under drive across a longer span, so a long rip or a long moulding run stays under control from entry to exit. The drive behind them is a 1050 W S6 / 750 W S1 motor on 400 V with eight standard speeds of 3.5, 5, 7, 10, 12, 17, 26 and 34 m/min, taken from a precise gear set that keeps each of those rates steady as the cutter loads.
Roller size and contact
Roller geometry is what four rollers buy, and the geometry is generous: all four rollers measure 120 mm in diameter and 60 mm in width. Spreading the same downforce across four contact bands rather than three lowers the pressure each roller has to apply for the same total grip, and the 60 mm width keeps that pressure over a broad strip of the board face instead of a narrow line. On long workpieces the practical result is fewer moments where the board is being driven by only one roller.
Adjustment through the dual rod device
Every working position on the SF444N-8 is reached from the dual rod device — height over the table, angle to the fence and reach across the machine all set from the same two rods. That angle setting is the working detail: canting the head a few degrees toward the fence turns part of the feed force into side pressure, which is what holds a long board against the guide rather than letting the tail wander at the end of the cut.
Mass and shipping envelope
At 60 kg net and 66 kg gross the SF444N-8 is 4 kg heavier than the three-roller SF344N-8, and the package is noticeably longer — 770 mm long against 560 mm, at 560 mm wide and 290 mm high. Both figures matter before delivery: the mounting column or table bracket must carry a 60 kg head without flexing, and the longer feed head needs clear travel over the table without fouling the fence or hood.
Supply and quotation
The SF444N-8 is catalogued in a single electrical version, the 400 V SF444N-8_400V under EAN 9120039900704, so a 400 V connection at the machine position is part of the installation. Price, delivery window, warranty terms and the exact contents of the crate for the SF444N-8 are confirmed at quotation.

უპირატესობები
- Four 120 mm rollers keep long boards under drive where a three-roller head loses contact
- Eight speeds from 3.5 to 34 m/min on a 1050 W S6 motor cover profiling through to fast ripping
- Same roller size (120 mm × 60 mm) as the SF344N-8, so wear parts are shared across both feeders
გასათვალისწინებელი
- Catalogued in a 400 V version only — no 230 V variant of the SF444N-8 is listed
- 60 kg net and a 770 mm long head demand a rated column and clear travel over the table; small saw benches will not carry the SF444N-8 comfortably
- Four rollers give no speed or power advantage over the SF344N-8 — the motor and speed range are identical, so the extra cost buys contact length only
