Reducing backlash needn't be such a drag
New nut designs from Abssac rely on a revolutionary cross cam design to eliminate backlash, maintain a high axial stiffness but simultaneously reduce drag friction.
To eliminate backlash often meant a sacrifice in drag torque - but not any more New nut designs from Abssac rely on a revolutionary cross cam design to eliminate backlash, maintain a high axial stiffness but simultaneously reduce drag friction

Backlash eliminated from rolled acme screws
The new Abssac XCT and XCF rolled acme screw nut designs rely on a revolutionary Cross Cam design, called the "Active Cam" to eliminate backlash
Normal split nut designs with a loaded spring between the two halves eliminate backlash, but inherently have high drag torques and lower thresholds where axial stiffness can be maintained.
The new XCT and XCF units eliminate these problems.
The new designs provide a bidirectional drag torque resulting in higher positional accuracy in both directions, and are also thermally balanced.
Another benefit is that they automatically adjust and compensate for wear maintaining features and benefits to system.
The new nut designs can be attached to the application via the integral flange mounted style nut or by the thread mounted version.
The nuts compliment precision rolled cold rolled formed stainless steel acme screws from 10 to 24mm diameter, combined with a range of leads in each diameter.
Sam Hopkins of Abssac says: "There is a real demand for high accuracy rolled acme screws, but traditionally nut designs have trailed behind in terms of performance".
"These new nut designs bring a low cost alternative to the designer whilst maintaining a high degree of performance".
"When you combine this with the massive range of rolled screw formats we offer we have a formidable package to offer the end user". Request a free brochure from Abssac ...
