MR85ZZ leje er en type miniature-kugleleje, der er populær inden for 3D-printning og andre præcisionsapplikationer. Det er et lukket kugleleje med en indvendig diameter på 5 mm, en udvendig diameter på 8 mm og en bredde på 2,5 mm.

MR85ZZ kuglelejet er kendt for sin glatte og præcise rotation samt dets evne til at håndtere høje rotationshastigheder. Det er lavet af holdbart materiale og er designet til at modstå belastning og slid over længere tidsperioder.

Dette kugleleje bruges ofte i små mekaniske systemer, som f.eks. 3D-printere, robotter, droner og lignende. Det hjælper med at reducere friktionen og sikrer en jævn bevægelse, hvilket er afgørende for nøjagtige og pålidelige bevægelser i disse applikationer.

MR85ZZ-kuglelejet er nemt at installere og vedligeholde. Det tilbyder også god beskyttelse mod støv og snavs på grund af sin lukkede konstruktion. Ved korrekt pleje og smøring kan dette kugleleje have en lang levetid og bidrage til optimal ydeevne i dine mekaniske systemer.

Bondtech SLS made Universal BL Touch Mount Recommended Component

This BL Touch mount is recommended to install the popular bed levelling sensor on our Bondtech DDX Direct Drive eXtruder for Creality. This PA12 version allows for higher working temperatures than its FDM counterpart.

The Universal version has a slot to enable adjusting the Z off-set to the bed and nozzle tip, thus enabling it to be used with all available hotends compatible with the DDX.

If you use a Copperhead or a Mosquito hotend, be aware we have available specific versions for those hotends.

• 1x 10079-60 SLS Universal BL Touch Mount for DDX

The Bondtech BMG extruder combines high performance and resolution with low weight. Together with our proven and highly celebrated Dual-Drive technology you can expect problem free material feeding.

The BMG works in both bowden and direct driven applications. Built-in fitting for the E3D hotend and fits Nema17 stepper motors. Please mind the bowden adapter is not included.

The housing parts are professionally SLS printed in nylon for maximum strength and precision.

This extruder only supports 1.75 mm size filament.

Bondtech Mini Geared BMG Extruder Features

The Bondtech BMG utilizes an internal gearing ratio of 3:1 together with precision cnc-machined Nickel coated Hardened Steel drive gears to give you a compact powerhouse for all your applications. Whether you require high resolution prints with small nozzles or high-flow prints with big nozzles the optimized gearing ratio combined with our industry leading drive gears provides unparalleled pushing power and lightning fast retractions in a lightweight and compact package.

Bondtech Mini Geared BMG Extruder

Our unique Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping in even the most demanding conditions. Bondtech users the world over will attest that even in prints with thousands of retracts our extruders perform flawless, with unmatched precision, and zero damage or degradation to the filament.

Multi-material capability

Our BMG extruder feeds all material with high reliability, from slippery nylons and soft TPU/TPE filaments to highly rigid and sometimes brittle carbon-filled high-strength materials. The extruder is designed for 1.75 mm filaments, but has been tested to ensure performance of filament from 1.5mm up to 2.0mm allowing for high reliability regardless of the tolerance of the filament used. The filament path is fully guided throughout the extruder body and the housing maintains tight tolerances to the drive gears mitigating the chances of Filament Misfeed when the hotend experiences increased back-pressure or highly flexible filaments are used.

Adjustable tension

The thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament. This gives you the power to adjust according to your preferences and to optimize for the type of material you are using.

Quick-Release

To be able to do material changes in a snap, simply activate the Quick-Release lever to release the tension and pull the material to be changed out of the extruder, keep it activated and insert the new material.

Multi-application design

This extruder can be used in a Bowden or direct setups and gives you the flexibility to choose what works best for your application. In addition it features an integrated hotend retention method compatible with the E3D-V6 hotends or others using the Groove Mount standard. Mounting your hotend is simple, secure, and wobble free by means of just two bolts.

Flexible mounting options

We have designed a standard mounting bracket, both in CNC and as a 3D printable part that you can download from our stl-archive for free. Our standard mount is CNC-machined in 3 mm aluminum for maximum stability. Please see below for available mounts.

The extruder fits any Nema17 stepper motor with a standard 5 mm shaft. For suitable stepper motors, please select one of the below or use your own motor.

This extruder is sold without motor.

• Weight without motor: 75g
• E-step value: 415

Bondtech Mini Geared BMG Extruder New Design Features

The Motor Gear is now made of Brass
The corrosion resistant material will stop the very low frequency of oxidation issues that happened to the steel gears.

The POM Gear attached to the Main Shaft is now Black
This is a pure aesthetical upgrade to mask out the dirt that shows too much on white.

The Push-Fit is now threaded
It can be removed and/or replaced to make it easier to solve clogs without ruining the BMG’s housing.
