Joyce/Dayton - Established 1873
Joyce Ball Screw Jacks feature a ball nut with integral ball bearings that recirculate along the surface of the ball screw. The significantly reduced friction between the ball nut and screw results in greater efficiency, with up to 2/3 less input torque required to move the load than a similarly rated machine screw jack.
Compared to Machine Screw Jacks, Joyce Ball Screw Jacks
- Require less motor horsepower
- Allow higher travel speed
- Provide an extended duty cycle
Joyce Ball Screw Jacks are available in translating screw or rotating screw (keyed for traveling nut) designs. Translating screws are available with threaded, load pad, clevis or plain ends. Options include limit switches, encoders, geared potentiometers, direct drive and reducer mounts, and protective boots. Joyce Ball Screw Jacks are ideal for single or multiple jack systems.
Unlike Machine Screw Jacks, Ball Screw Jacks are not self-locking. Because they will lower under load, a brake motor or other external braking mechanism is required.

The closing system consists of a self-cleaning ball which is lifted by the fluid and guided to a lateral housing, completely out of the way. This system ensures an unrestricted flow, even for liquids carrying waste materials, without risk of a blockage. This all-purpose range is also suitable for use with aggressive liquids and in industrial processes.

Changing technique for rapid die change:
Die changing technique using roller bars, ball bars, ball inserts, carrying consoles and die carts. Everything to allow easy and safe die changing.
Carrying consoles – Die changing consoles:
Consoles to permit easy, safe and efficient die change on the press bed. Carrying console, either swivelling or supported, for large weights of up to 250 kN. Set-up times reduced to a minimum, this guarantees more efficient use of the machine and a high degree of operational safety.
Die carts for rapid die change:
HILMA die carts facilitate the handling of heavy dies. All the robust die carts are designed for changing dies weighing up to 40 kN on presses and machines without risk of accidents, without using force and in an efficient (time-saving) manner. Their solid construction guarantees a long service life. The die carts designed to withstand the harsh conditions prevailing in a press shop are very reliable “partners”.

Bespoke 'T' & 'B' Block Systems for Rapid Tool
Change. Roll on - Roll off facility dramatically reduces
tool changeover times.
Advantages:
Roll on - Roll off facility:
- Dramatically reduces tool changeover times.
- Eliminates tool and press bed damage.
- Allows accurate tool positioning.
The Omnitrack 'T' & 'B' Block systems are designed to facilitate
rapid tool change on any type of press / machine.
The standard format consists of housed spring-loaded Ball Units
which are inserted into the tenon slots of the press. When in the
raised position, the balls protrude above the bed level allowing
the tool to be rolled onto the bed and positioned accurately.
When clamping is carried out the balls retract, lowering the tool
onto the press bed. When clamping is released the balls lift the
tool, allowing it to be rolled from the press.
Standard slot dimensions for 'T' & 'B' bars are shown. We also
manufacture these systems for non-standard slots. Ball pitch,
deflection, load and clamping are application specific. Contact
us for a bespoke solution.

The slots in the press table define the shape and size of the required ROLLBLOC die lifters.
ROLLBLOC ball version offer the advantage of being able to easily move dies in any direction. In conjunction with different die formats, this advantage ensures particularly short setup times.
ROLLBLOC roller version offer double the load bearing capacity. They enable exact linear transfer of the die. This linear technology requires accurate die positioning during transfer to the die table or to the die loading arms.
To further reduce rolling friction, we recommend hardened strips on the underside of the die. Unlike the ball version, the ROLLBLOC die lifter with rollers can also be used in the die base plate (overhead installation).

Ball Lenses
Ball lenses are used for various tasks such as improving the coupling between optical fibers and the emitters or detectors they interface with. Standard size lenses range from 1.0mm to 5.0mm. Custom-made sizes or special materials are also available. All Ball Lenses can be ordered with full-surface anti-reflection (AR) coating..
The effective focal length of a ball lens is given by the following formula:
BFL = F – D/2 and EFL = nD/4(n-1)
The Numerical Aperture, NA, of a ball lens is dependent on the focal length of the ball and on the input diameter, d.
NA = 2d(n-1)/nD

Drum Lenses
A Drum Lens is a variation of a ball lens where a portion of the ball is ground down to a smaller diameter. These lenses are used in similar applications to those of ball lenses. The drum lens adds the ability to handle and package it in a different way.
