Low Friction Ceramic Guide Blocks for Bandsaws with High Precision
Tolerance
Tag key words : Ceramic guide block
Ceramic Guide Blocks are made of Aluminum-Oxide - the same material used to make
ceramic products for NASA. They create far less friction to provide
a cooler running blade and truer tracking. You'll get guide block
seat tolerance of +/-.005. Outlasts every other guideblock on the
market!

Carter Band Saw Guides are a popular upgrade option for most
band saws. What are they? Carter guides are designed to add stability to the
blade, especially in tight curves. Unlike the stationary guide
blocks that most of us are used to seeing, they use rollers to
guide the blade, both above and below the table.
Ceramic Guide Blocks TECHNICAL DETAILS
These blocks will only fit 14" Delta or Jet Band-Saws.
Mingrui Ceramic Guide Blocks are made from zirconia and alumina ceramic . They contain no
ceramic fibres, and as a result, offer better insulation
performance than comparative competitive products.
Ceramic Guide Blocks key features are:
- Excellent strength and insulating properties
- Lower thermal conductivity than competitive vermiculite block
products
- Resistance to aluminium cryolite attack
Ceramic Guide Blocks are ideal as a solution:
- Melting and holding furnaces for iron, steel and aluminium
industries
- Aluminum Pot Cells
- Back-up to furnace linings
See our product datasheets for more information on our range of
structural block insulation products or contact us to discuss your
requirements.
Ceramic Guide Blocks
■Good smoothness / flatness with less porosity. Excellent in
adhesion with thin film and thick film materials.
Ceramic Guide Blocks with Less variance in outline, plate thickness, slit pitch, etc.
■Minimal warpage, bending, and undulation.
■Physical and chemical properties are stable even under a hot
environment. Excellent in thermal shock resistance. High thermal
conductivity and coefficient of thermal expansion similar to that
of silicon.
■Superior mechanical strength. Products with higher mechanical
strength are also in our lineup.
■Excellent resistance against oil and chemical.
■Excellent in insulation properties, high dielectric breakdown
voltage, high surface resistivity / volume resistivity, and small
dielectric constant.
■Stable breaking strength, and less variance in shape or
dimensions.
■The high reflective substrate, especially suitable for optical
applications such as LED, is also available.
Applications of Ceramic Guide Blocks
Ceramic block can be used for a device or equipment in the special
environment such as Power isolation, high temperature protection,
durable wear, high and low temperature impact etc...and for the
different device should be requiry different ceramic block shapes,
like: some device need the round sheet be machining 8 hole to
fasten to the box.
Ceramic Guide Blocks offers consistently reliable and convincing performance even when
subject to high thermal and electrical loads in terms of its:
Thermocycling capability
Thermal shock resistance
Flexural strength
Surface quality
Thermal conductivity
