  6. Tolerance: Specified Dimension -0" + 0.006"
  7. The Boschert Classic Series Safety Chuck has been the standard of the industry since Boschert invented the Safety Chuck in 1948. This is a rugged Safety Chuck with lots of capacity built in for future upgrades. The concentricity of this unit is comparable with the Boschert Value Master. These units feature square openings case hardened to Rockwell 56 C. This Safety Chuck series is best suited to slow running unwinds and winders. The Boschert Safety Chuck design employs a tilting hand wheel to lock the end of the customer’s square journal in the square opening of the Safety Chuck. This is a superior design because it allows the load bearing surface of the customer’s journal to be closer to the first set of bearings in the Safety Chuck housing. Other Safety Chuck designs require room behind the load bearing area of their Safety Chuck. They need the space to allow a locking collar or cam to move back in order to exchange journals. Such design places the load bearing area of their Safety Chuck farther away from the first set of bearings. This outboard design causes greater stress to the Safety Chuck drive shaft and any eccentricity to the roll shaft is magnified in wear to that design Safety Chuck.

  1. Maximum Eccentricity 0.004"
  2. Chrome Plated Steel Handwheel
  3. Rubber Finger Guard
  4. VT Parts Replaceable Insert

  7. This Safety Chuck features the patented Replaceable Insert feature by Boschert. With the Replaceable Insert feature the customer can specify a square opening, a triangular shape opening, hex shape, or just about any shape the customer requires.

    The advantage of this model Safety Chuck is that it is designed for higher speed applications. Because of the Boschert design Replaceable Insert, this Safety Chuck offers a closer concentricity than the standard mill cut square opening our competitors offer. Closer concentricity means less vibration during the run, and greater life because of less wear, for both the end of your roll shaft and the opening/pocket in the Safety Chuck.

Features: VT Style Safety Chuck
  1. Maximum Eccentricity 0.003"
  2. Chrome Plated Steel Handwheel
  3. Rubber Finger Guard
  4. VT Parts Replaceable Insert
  5. Hardened to your specification Available Off The Shelf in 50 Rockwell C
  6. Tolerance: Specified Dimension -0" + 0.000984"
  7. Tight tolerances between the roll shaft journal and the pocket of the Safety Chuck make for smooth operation. Tighter tolerances result in less movement in the pocket of the Safety Chuck. Reduction of movement results in greater life of those parts and less stress to the operation quality control sensors.

    The triangular shape of the VT-6 provides for self-centering loading. The design is wider at the top allowing faster, easier loading and unloading. This creates faster turnaround and greater confidence for the operator in his equipment.

    This triangular shape only allows movement insider the pocket two times per revolution instead of four times per revolution with a square shape. A roll shaft journal falls inside the pocket every revolution, that distance which is the tolerance. With less movement in the pocket, you get greater life for your roll shaft journal and greater life for the pocket of the Safety Chuck. The aggressive action between the journal and the pocket is not as severe because of the tight fit! Easier loading... smoother operation... get the full value of the Boschert VT-6 Safety Chuck.
